How to Find Candidates for Hard to Fill Positions
We work on a lot of roles that someone, somewhere has already tried and failed to fill. Sometimes the brief is unrealistic. Sometimes the sourcing strategy was copy-pasted from the last hire. Sometimes the right candidates exist but nobody's reached them yet. We cover the real strategies for finding candidates in hard to fill positions — including how executive search firms find C-level candidates, how to reach passive and niche talent, and what diverse candidate sourcing looks like in practice, rather than in theory.
Some roles are hard to fill for good reasons.
The candidate pool is genuinely small. The skills required are rare, recently in demand, or both. The role sits at a seniority level where most of the people who'd be right for it aren't looking. Or it requires a combination of things — technical depth, commercial acumen, a specific sector background — that narrows the field considerably before you've even started.
And some roles are hard to fill for bad reasons.
The brief describes a unicorn that doesn't exist at the offered salary. The sourcing strategy is "post it on LinkedIn and wait." The job ad reads like it was written by someone who's never done the role. The previous three people who tried to fill it all started from scratch rather than building on what the others learned.
Before you change your sourcing strategy, it's worth working out which type of hard you're dealing with. Because the fix for a genuinely scarce candidate pool is completely different from the fix for a process that's not reaching the right people.
Why Some Positions Stay Stubbornly Unfilled
Most UK employers report difficulty filling roles due to a lack of skilled talent.
The picture is even more acute in specific sectors. IT and data skills remain the hardest to find in the UK — a position unchanged for the last five years, despite not even ranking in the top ten most difficult skills to source a decade ago. Many IT firms reported plans to hire, but most of the same organisations said they were struggling to find the qualified candidates they needed.
That gap — between hiring intention and hiring reality — is what hard to fill looks like in practice.
In the UK, hard to fill vacancies are most prevalent in Education, Health and Social Work, and Manufacturing, though the problem runs across virtually every sector that requires specialisation, experience, or both.
But how much of that difficulty is a market problem versus a process problem. Because a significant proportion of hard to fill roles stay unfilled not because the candidates don't exist, but because the people doing the hiring are looking in the wrong places, presenting the role in the wrong way, or running a process that the right candidates have no reason to engage with.
Are Technical Candidates Easy to Find in the UK? (Short Answer: No)
If you're hiring for technical roles in the UK, you already know the answer.
The most in-demand technical roles — cloud infrastructure, cybersecurity, AI and machine learning, data engineering — are being chased by more employers than the market is currently producing. And the candidates who do exist know it. They receive multiple approaches. They have options. They are not, as a rule, impressed by a generic InMail that starts "I came across your profile and thought you'd be a great fit."
What this means practically: finding good technical candidates requires more than a better job ad. It requires going to where those candidates actually are — specialist communities, open source platforms, GitHub, technical meetups, university programmes producing relevant graduates — and approaching them in a way that treats them as the scarce, in-demand professionals they are.
It also means being honest about what you're offering. Technical candidates, more than almost any other group, can see through a vague employer value proposition. If your tech stack is interesting, say so. If it's not, say something else that is. If the role involves building something genuinely challenging, lead with that. If it involves maintaining legacy systems, be upfront — the right candidate for that role exists, and they won't thank you for disguising it as something else.
How to Find Passive Candidates (The Ones Not Responding to Your Ads)
Passive candidates — people who are currently employed, not actively looking, but potentially open to the right opportunity — represent somewhere around 70% of the total talent market, which makes proactive headhunting essential for any role where the best people are unlikely to be applying to job boards on a Tuesday afternoon.
The challenge is that passive candidates require a completely different approach from active ones. You're not responding to their interest — you're creating it. And the bar for creating genuine interest in someone who's currently comfortable is significantly higher than the bar for responding to someone who's already looking.
Here's what works.
A credible, personalised approach
Passive candidates receive a lot of generic outreach. The ones worth reaching receive even more. What cuts through is specificity — evidence that you actually know who they are, what they've done, and why this particular role is relevant to them at this particular point. Not "I think you'd be a great fit" but "I noticed you led the migration to X architecture at your current company — we're doing something similar at scale and I thought it might be worth a conversation."
The right messenger
A cold message from an unknown company HR team lands differently from an approach via a trusted recruiter the candidate has worked with before, or a warm introduction from a mutual contact. The relationship context matters as much as the message content.
Timing
Passive candidates move when something shifts — a new manager they don't gel with, a project that's concluded, a strategic change in their company's direction. You can't always know when that shift has happened, but consistent, low-pressure contact over time means you're in the conversation when it does.
Something worth moving for
This sounds obvious and gets ignored constantly. A passive candidate who's happy in their current role has a real switching cost — comfort, familiarity, relationships, certainty. The role you're offering needs to be meaningfully better on dimensions they actually care about, not just marginally different. If the salary is the same and the commute is longer, the answer is almost certainly no.
How to Find Niche Candidates: Strategies for Specialist Roles
Niche roles — specialist technical positions, rare functional expertise, roles that sit at the intersection of two unusual disciplines — require sourcing strategies that go well beyond standard channels.
The best way to find niche candidates is to go where those candidates congregate before they're candidates.
Professional communities and associations
Most specialist fields have professional bodies, online communities, Slack groups, Discord servers, or forums where practitioners discuss their work, share resources, and build reputations. These communities are not recruitment channels — and treating them as such will get you ignored or worse. But being genuinely present in them, understanding the conversations happening there, and building relationships over time is how you get to know who the strong practitioners are before a role opens.
Conferences and specialist events
Speakers at industry conferences are, by definition, people with something worth saying in their field. The attendees are people invested enough to spend time and money staying current. Both groups are worth knowing.
Academic and research pipelines
For genuinely frontier technical roles — advanced AI, quantum computing, specialised engineering disciplines — the candidate pipeline often runs through university research departments rather than the job market. Building relationships with relevant departments before you need to hire from them is worth the investment.
Referrals from within the field
People who are excellent at niche roles tend to know other people who are excellent at niche roles. A strong hire, or even a strong candidate who wasn't quite right for the last role, is worth asking: who else do you know in this space? A credible personal recommendation from within a specialism carries more weight than any number of job ads.
Competitor mapping
For roles where the talent pool is small and concentrated, it's usually possible to identify the companies and teams most likely to contain the right person. That narrows the sourcing problem considerably — from "find anyone in the market" to "reach three or four specific people at six specific organisations." The approach then becomes a targeted outreach exercise rather than a broad search.
How Do Executive Search Firms Find C-Level Candidates?
C-suite and senior leadership hiring is its own category, and it works almost nothing like standard recruitment. Understanding why is useful whether you're hiring a CEO or just wondering what you're actually paying a retained search firm to do.
Nearly all executive-level candidates are passive. Most senior leaders are not actively applying for roles — they're open to the right opportunity at the right time. This is why executive search relies on direct outreach, timing, and relationship rather than job ads.
The process starts with market mapping — recruiters map target companies, reverse-engineer org charts, and identify executives in comparable roles across competitors and adjacent markets. This isn't surface-level profile browsing. It's research-led intelligence that produces a specific, justified shortlist rather than a broad pool.
From there, executive search companies actively connect with passive candidates and keep them engaged with industry news, career conversation, and subtle opportunities over time — so that when the right role opens, they're already in a relationship rather than making a cold approach.
The outreach itself is deliberately different. Outreach typically occurs early morning or evening when executives check personal messages, with messages emphasising mutual connections, shared industry experience, or specific achievements that demonstrate deep research.
What this means if you're trying to find a C-level candidate without a specialist firm: you're largely trying to replicate a relationship and intelligence network that established search consultants have spent years building. That's possible in theory. In practice, for genuinely senior roles, the access that a well-connected search firm has to candidates who will take their call — and seriously consider a role because of who's presenting it — is difficult to replicate from a standing start.
The retained model matters here too. Executive roles are filled via networking and headhunting in over 80% of cases — which means if you're relying on a job ad for a CFO or CTO search, you're fishing in a very small pond.
Diverse Candidate Sourcing Strategies That Work
Finding diverse candidates is talked about a great deal and done well considerably less often.
The usual approach — post the role on a diversity job board and add "we are an equal opportunities employer" to the footer — is not a diversity sourcing strategy. It's a compliance exercise. It produces minimal results and then gets used as evidence that "we tried."
Genuine diverse candidate sourcing requires examining the process, not just the channels.
Audit where your current pipeline is coming from
If 90% of your applicants come from the same two or three sources, you're not reaching a representative pool regardless of how your job ad is worded. Map your sources and then identify which communities, networks, and channels you're systematically absent from.
Remove the barriers that filter out diverse candidates before they apply
Degree requirements for roles that don't functionally need a degree. Job descriptions that use language associated with a particular type of candidate. Portfolio or work-sample requirements that disadvantage people who've had less access to high-profile projects. These aren't malicious — they've often just never been examined. Examine them.
Build relationships with organisations that work with underrepresented talent
Professional networks, mentorship programmes, bootcamps, apprenticeship schemes, and graduate programmes specifically designed to bring underrepresented groups into specific industries are often significantly underused by employers. These aren't charity relationships — they're talent pipelines that most of your competitors haven't bothered to build.
Structured assessment protects diversity at the evaluation stage
Diverse sourcing without structured assessment is only half the job. Unstructured interviews systematically disadvantage candidates who don't match the unconscious template interviewers have of "the kind of person who does this job." Consistent questions, pre-agreed criteria, and scored evaluations mean the assessment reflects what the role actually requires rather than who feels familiar.
Widen the definition of relevant experience
Skills-based hiring — assessing what a candidate can do rather than the specific path they took to learn it — consistently widens the diversity of successful candidates because it breaks the reliance on credential and company name as proxies for capability. ManpowerGroup has argued that skills-based hiring has the potential to alleviate talent shortages, drive innovation, and create more diverse workforces simultaneously — which makes it one of the few approaches in recruitment that genuinely does multiple things at once.
When Standard Sourcing Has Run Out of Road: What to Try Next
You've posted the job. You've searched LinkedIn. The pipeline is thin, wrong, or both. Here's where to go next.
Revisit the brief
Before trying a new channel, check whether the problem is the brief rather than the market. A role that's been live for six weeks with a weak pipeline is often one where the requirements are unrealistic for the salary, the role title doesn't match what the job actually is, or the employer value proposition doesn't give anyone a reason to leave something comfortable. These are fixable problems, but not by sourcing harder.
Go to where your candidates work, not where they search
For most specialist roles, the candidates you want aren't actively searching. They're working. GitHub, specialist technical forums, published research, conference speaker lists, industry publications — these are directories of people who are demonstrably good at the thing you need, none of whom are currently refreshing job boards.
Talk to the people already in your network
Your current team, your recent hires, your professional contacts — these are people with first-hand knowledge of who the strong practitioners are in their field. Referral programmes with a meaningful incentive exist for good reason. A warm recommendation from someone you trust is worth ten cold applications from people you don't know.
Reconsider your geography
Remote and hybrid working has substantially expanded the geographic reach of most talent searches. If you're looking for a specific technical skill in a particular city and finding the pool is thin, the pool might be larger two cities over and perfectly reachable. Not every role can be done remotely, but it's worth checking whether geography is an artificial constraint before deciding the candidate doesn't exist.
How SquareLogik Approaches Hard to Fill Roles
When we take on a role that's already beaten someone else, the first thing we do is understand why.
Not because we assume the previous effort was wrong, but because the answer usually tells us something important. Was the pipeline thin because the market is genuinely scarce? Because the sourcing was limited to active candidates? Because the brief was realistic but the presentation of the role wasn't compelling? Because the process was slow enough that good candidates dropped out before reaching an offer?
Each of those problems has a different solution. And applying the solution to the wrong problem is how a hard to fill role stays hard to fill for another three months.
We use AI to extend sourcing reach — identifying passive candidates and building market maps faster than manual research allows. We use human judgement to decide whether those candidates are actually worth approaching, and to make an approach that's worth responding to. And we track what happens after placement, because the whole point of finding the right person for a difficult role is that they actually stick.
If you've got a role that's been sitting open longer than it should, or one you haven't even started on because you already know it's going to be difficult — we're worth talking to. Honestly, the harder the better. The straightforward ones are less interesting.
Frequently Asked Questions
How do you find candidates for hard to fill positions?
Start by diagnosing whether the difficulty is a market problem or a process problem. If the candidate pool is genuinely scarce, standard sourcing channels won't help — you need proactive outreach to passive candidates, specialist community engagement, and targeted competitor mapping. If the pipeline is thin because the process isn't reaching the right people, the fix is in the sourcing strategy and the job presentation, not in trying harder with the same approach. Most hard to fill roles involve both issues to some degree.
How do executive search firms find C-level candidates?
Through a combination of market mapping, long-term relationship building, and targeted direct outreach to passive candidates — most of whom are not looking and would not respond to a standard job ad. Executive search consultants research competitor organisations, identify leaders in comparable roles, and make personalised approaches via trusted channels. The value is largely in the access and the credibility: a well-connected search consultant's call gets answered in a way that a cold approach from an unknown company HR team typically doesn't.
How do you find passive candidates?
Proactively, and with patience. Passive candidates aren't browsing job boards — they need to be reached directly via professional networks, warm introductions, and consistent relationship-building over time. What cuts through generic outreach is specificity: demonstrating genuine knowledge of what they've achieved and why this particular role is relevant to them now. Timing matters too. Passive candidates move when something shifts in their current situation. Consistent, low-pressure engagement means you're present when that shift happens.
Are technical candidates easy to find in the UK?
No, and the gap is widening. IT and data skills have been the hardest to find in the UK for five consecutive years, with 75% of tech firms reporting difficulty sourcing qualified candidates even while planning to hire. The most in-demand skills — cloud, AI, cybersecurity, data engineering — are being pursued by more employers than the market is producing. Finding strong technical candidates requires going beyond job boards to specialist communities, open source platforms, academic pipelines, and warm referrals from within the field.
What are the best diverse candidate sourcing strategies?
The most effective approach combines widening the sourcing channels with removing the structural barriers that filter out diverse candidates before and during the process. That means auditing where your pipeline actually comes from, building relationships with networks and programmes that serve underrepresented groups, removing unnecessary credential requirements, and implementing structured assessment that evaluates candidates against consistent criteria rather than cultural familiarity. Skills-based hiring — assessing capability rather than credentials — consistently improves diversity because it breaks the reliance on educational background and employer name as proxies for potential.
What is the best way to find niche candidates?
Go where they are before they're looking. Specialist professional communities, industry conferences, academic and research pipelines, and referral networks within the field are all more effective than job boards for genuinely niche roles. The candidates you want are typically visible in their field — they speak at events, publish work, contribute to communities — long before they're candidate. Building a presence in those spaces before you need to hire gives you warm relationships rather than cold outreach when a role opens.
How do you find a C-level candidate without using an executive search firm?
With difficulty, and it's worth being honest about that. C-suite candidates are overwhelmingly passive — over 80% of executive roles are filled through networking and headhunting rather than applications. Without an established network and the credibility that comes with a known search firm, reaching and engaging the right people is substantially harder. Warm introductions through board members, investors, and senior advisors are the most viable route. If the role is genuinely strategic and the cost of a wrong hire is significant, a specialist search firm is usually worth the fee.
Some roles are hard to fill for good reasons.
The candidate pool is genuinely small. The skills required are rare, recently in demand, or both. The role sits at a seniority level where most of the people who'd be right for it aren't looking. Or it requires a combination of things — technical depth, commercial acumen, a specific sector background — that narrows the field considerably before you've even started.

Specialist professional communities, industry conferences, academic and research pipelines, and referral networks within the field are all more effective than job boards for genuinely niche roles. The candidates you want are typically visible in their field — they speak at events, publish work, contribute to communities — long before they're candidate. Building a presence in those spaces before you need to hire gives you warm relationships rather than cold outreach when a role opens.
How do you find a C-level candidate without using an executive search firm?
With difficulty, and it's worth being honest about that. C-suite candidates are overwhelmingly passive — over 80% of executive roles are filled through networking and headhunting rather than applications. Without an established network and the credibility that comes with a known search firm, reaching and engaging the right people is substantially harder. Warm introductions through board members, investors, and senior advisors are the most viable route. If the role is genuinely strategic and the cost of a wrong hire is significant, a specialist search firm is usually worth the fee.

How to Find Candidates as an SME Competing With Larger Employers
SMEs can't outspend large employers. But they can out-offer them on things that may matter more. Here's how to find candidates as a small business competing for the same talent.
SMEs assume the competition is about money and brand recognition. A large employer has both. SME has neither. Therefore, the SME loses.
This logic is tidy, plausible, but mostly wrong.
The candidates who are exclusively motivated by salary and brand prestige are going to the large employer regardless of what you do. But that is not most candidates.
Most candidates (particularly the experienced, mid-career professionals who make the best hires) are weighing a more complex set of factors:
- Proximity to decision-making.
- Variety of work.
- Speed of progression.
- The ability to see the impact of what they do.
- A culture that doesn't require three approvals to change the font on a slide.
On every one of these dimensions, a well-run SME can and regularly does outperform a large employer. The problem is that most SMEs don't know this, don't say it, and therefore don't attract the candidates for whom it would be decisive.
This article is about fixing that.
The Advantages of Recruiting as an SME
Before sourcing a candidate, get clear on what your genuine competitive advantages are.
SMEs offer things that large employers structurally cannot.
A new hire at a 40-person business will meet the founder in their first week, probably work directly with senior leadership, and have their work visible to the whole organisation almost immediately. A new hire at a 40,000-person business will spend three months learning which Slack channel to use.
Speed of progression is real and measurable.
An ambitious person who joins a growing SME can move from a mid-level role to a leadership position in two to three years if they perform. The same person at a large employer is probably queuing behind people who got there before them, waiting for a headcount approval, or competing in a talent programme with forty other people who are also quite good.
Variety of work is another genuine differentiator.
At a large employer, roles are defined, scoped, and bounded. At an SME, people routinely do things that weren't in their job description because the business needs it and they're the right person. For candidates who want breadth and interest, this is genuinely attractive — not a consolation prize.
The reason these advantages don't translate into hiring outcomes for most SMEs is that they don't communicate them. The job ad lists the same competencies any large employer would list. The interview process is the same. The offer lands next to a larger one and loses on the only dimension being compared.
Lead with what you actually win on.
Write Job Ads That an SME Would Write
Large employers write large employer job ads. They describe the role in the abstract, list twenty requirements, reference the company values from the careers page, and promise a "dynamic and fast-paced environment," which has described every job posted since the internet was born.
An SME job ad written honestly is a competitive advantage. Write it like a person who knows the role, the team, and the culture... because you do.
- Describe the specific work the person will be doing in the first three months.
- Name the team they'll be joining, what the team is working on, and what's interesting about the problem.
- Be honest about the hard bits, like the pace, the ambiguity, the fact that there isn't an established process for everything and sometimes they'll have to build it.
The candidates who read that and think "that sounds like exactly what I want" are your candidates. The ones who think "that sounds chaotic" were not going to thrive there anyway.
- Also, mention salary. Not a range so wide it communicates nothing, but a realistic one.
Candidates filter by salary before they read anything else. Hiding it costs you application volume at the relevant level and wastes everyone's time at the relevant stage.
Specificity attracts the right people and filters out the wrong ones. A generic job ad does the reverse.
Use the Sources Where Your Candidates Are
As an SME, if you use the same channels large employers use, you can't wonder why you're competing with vastly better-known names for the same pool of active jobseekers.
Your own network is the most underused source you have.
The founder, the leadership team, the existing employees — these people know people. A direct message from a founder to someone they respect in the industry, explaining what they're building and why they'd be a good fit, converts at a rate that no job board matches. It is also free.
Employee referrals are the extension of this. Your current team knows the field. They know who the good people are, who might be ready for a move, who would fit the culture. A referral scheme with a meaningful incentive and a dead-simple process for making introductions consistently produces the highest-quality candidates at the lowest acquisition cost. Most SMEs have a referral programme in theory. Most of them don't actively use it.
Niche job boards and communities outperform generalist boards for specific roles.
A software engineering role posted in a relevant developer community will reach people who are engaged with the field and not getting lost in recruiter noise. A marketing role posted in a specialist marketing community reaches people who care enough about their discipline to be there. LinkedIn remains useful for direct sourcing — searching for people in the right roles at the right organisations, and reaching out with something specific and personal rather than a template.
Local presence matters more for SMEs than for large employers.
A large employer with a recognisable name can hire nationally without much effort. An SME hiring locally benefits from being known in its community from:
- Sponsoring relevant events
- The founder being a visible presence in the local business network
- The team attending industry meetups.

Use Speed to Your Structural Advantage
One thing you can do as an SME can do that most large employers cannot is move fast.
A large employer running a competitive process involves multiple stakeholders, HR sign-off at various stages, a compensation committee review, and an approval chain for the offer. The candidate experience is often measured in weeks between touchpoints. The offer, when it arrives, has been through four people and taken eleven days to generate.
An SME can interview on Thursday and offer on Friday. The decision-maker is in the building. The approval chain has one step. The offer is a conversation rather than a document that needed three rounds of review.
This is not a small advantage. The candidates worth hiring are almost always running parallel processes. They have other conversations happening. The employer who moves decisively communicates something about how the organisation makes decisions. The one that takes three weeks to confirm a second interview communicates something too.
- Map your hiring process and identify where time is being lost.
- Commit to 48-hour feedback windows.
- Pre-book interview slots before candidates are confirmed.
- Have the offer conversation ready before the final interview happens, not after.
Speed doesn't compromise quality. But indecision after a thorough process does.
Build an Employer Brand Without a Budget
An SME employer brand is built from specificity, not spend.
Candidates research employers before applying and before accepting. What they find about you on LinkedIn, on Glassdoor, from people they know, etc., shapes whether the conversation goes anywhere. You don't need a careers microsite or a video series. You need enough genuine, specific content about what it's like to work there that a curious candidate can find it.
That might be the founder writing honestly on LinkedIn about what the company is building and why. It might be the team posting about the work they do. It might be a handful of authentic employee testimonials — not corporate-approved soundbites, but real accounts of what the role involves and why the person is still there.
Glassdoor matters. A company with three reviews, two of which are complaints, is a company that loses candidates at the research stage. Encouraging current employees to leave honest reviews (not pressuring positive ones, but making it easy and normal) builds a profile that converts curious candidates into applicants.
Lastly, specificity beats polish. A founder who writes one honest, thoughtful post about what they're building and why will reach more of the right people than a careers page that could have been written for any company.
Consider Working With a Specialist Recruiter
For roles where the right candidate is likely to be passive (currently employed, not looking, not going to find you through a job ad) a good recruiter with relevant market relationships changes the equation.
The value isn't the job board access. Any SME can post to job boards without help. The value of a recruitment agency is in the ability to:
- Reach ideal candidates who aren't visible through advertising
- Make a credible approach that gets a response
- Present your opportunity persuasively to someone who had no plans to move
For an SME competing with large employers in a specific talent market, a recruiter who knows that market and has existing relationships within it is levelling the playing field in the most direct way available. The large employer has brand recognition working in their favour. The recruiter has a relationship and a credible pitch working in yours.
The economics make most sense for roles that are hard to fill, business-critical, or where the cost of leaving the position vacant is significant. For broadly available roles with active candidate pools, the SME's own network and direct advertising will usually suffice.
How SquareLogik Works With SMEs
We work with a number of SMEs who are hiring in markets where larger and better-known employers are also hiring. Our role in those searches is not to help them compete on resources they don't have, but to help them compete on what they do have, and to reach the candidates for whom those things are decisive.
That means:
- Understanding what makes the opportunity compelling before we approach anyone
- Reaching passive candidates who wouldn't find the SME through a job board
- Moving with the pace that SME decision-making allows, which is often considerably faster than the large employer on the other side of the same search
If you're an SME finding it hard to attract the right candidates, we can assure you that the problem is not the size of your organisation, but the story being told about it, and where that story is being told.
We can help you with that.
Frequently Asked Questions
How can SMEs compete with large employers for talent?
By leading with advantages that large employers structurally cannot offer: proximity to decision-making, genuine breadth of work, speed of progression, and a direct line between individual contribution and business outcome. SMEs that try to compete on salary and brand recognition with larger employers lose. Those that lead with what they genuinely win on, and communicate it specifically and honestly, attract the candidates for whom those things are more important than the employer's name recognition.
Where should SMEs find candidates?
Start with your own network of founders, leadership, and current employees who know relevant people in the field. Referral schemes with meaningful incentives produce high-quality, low-cost candidates consistently. Niche job boards and professional communities outperform generalist boards for most specialist roles. LinkedIn is useful for direct outreach when the message is specific and personal. For passive candidates in scarce markets, a specialist recruiter with relevant relationships is the most direct way to reach people who won't find you through advertising.
How do you write a job ad that attracts candidates to an SME?
Write it like a person, not a large employer. Describe the specific work the person will do in the first three months. Name the team, the problem, and what's genuinely interesting about it. Be honest about the hard bits such as the pace, the ambiguity, the lack of established process in some areas. Include a real salary figure. Specificity attracts the candidates who are actually right for the role and filters out those who aren't, which is exactly what a job ad should do.
Is speed of hiring actually an advantage for SMEs?
Yes, significantly. The candidates most worth hiring are almost always running parallel processes. An SME that can interview on Thursday, offer on Friday, and have a signed contract the following week is communicating something about how decisions get made there — and is consistently securing candidates that slower-moving processes lose. Pre-booked interview slots, 48-hour feedback windows, and a decision-maker who is in the building and available make speed possible without compromising the quality of the assessment.
How do SMEs build an employer brand without a big budget?
Through specificity rather than spend. A founder writing honestly on LinkedIn about what the company is building. Team members posting about the work they do. Authentic Glassdoor reviews from current employees. A careers page that describes real work rather than aspirational values. None of this requires a marketing budget. It requires the willingness to be specific and honest about what working there is actually like, which is a lower bar than most SMEs set themselves and a higher bar than most of their competitors clear.
When should an SME use a recruitment agency?
When the right candidate is likely to be passive (currently employed and not looking) and direct advertising won't reach them. When the role is hard to fill and the cost of leaving it vacant is significant. When the SME is competing in a talent market where larger employers have more brand recognition and the recruiter's market relationships level the playing field. For broadly available roles with large active candidate pools, the SME's own network and direct advertising will usually produce sufficient results without agency support.
Why Your Job Ads Aren't Finding the Right Candidates
Most job ads describe a role rather than attract the right person for it. Here's what's filtering out the candidates you want and pulling in the ones you don't.
Most job ads are written for the wrong audience.
They describe the role in terms the hiring manager understands. They list the requirements the HR team agreed on. They include the values from the company's website. They promise a competitive salary and a collaborative environment.
And then they go live, and either nothing happens or the wrong people apply.
The reason is not the platform, the timing, or the algorithm. The reason is that the ad was written as a document about the role rather than a communication aimed at a specific person. Those are different things, and the difference determines whether the right candidates recognise themselves in it and apply.
Before diving in, you may also be interested in our article on building a talent pipeline before you need it.
A Job Description Is Not a Job Ad
This is the root cause of most underperforming job ads and it is almost never discussed.
A job description is an internal document. It defines the scope of a role, the responsibilities, the reporting line, and the requirements. It exists for HR, for the hiring manager, for compliance purposes. It describes the job from the employer's perspective.
A job ad is an external communication. It exists to persuade a specific type of person that this opportunity is worth their time. It describes the role from the candidate's perspective: what they will actually do, what they will learn, what impact they will have, and why this particular role at this particular organisation is worth considering over the alternatives they have.
Most organisations write a job description and post it as a job ad. The result is a document that is technically accurate and practically useless for attracting the people it needs to attract.
The candidates you want are reading that ad and making a decision in about thirty seconds. If what they find is a list of responsibilities and a requirements section, they are not getting enough signal about whether this is actually for them. So they move on. The candidates who apply are often those with lower standards for what they'll pursue, because they'll apply to anything that roughly fits.
You're Advertising the Requirements, Not the Opportunity
Here is a thing that appears in almost every underperforming job ad.
"The ideal candidate will have five or more years of experience in a relevant field, a proven track record of delivering results, excellent communication skills, and the ability to work independently and as part of a team."
This sentence contains no information. It is a description of every employed professional in the country. It tells a candidate nothing about whether this role is right for them, whether the work is interesting, or whether the organisation is worth considering. It is filler that exists because someone had to write something.
The requirements section of a job ad should exist to filter, not to describe. Its job is to make the right candidates recognise themselves and make the wrong ones self-select out. A list of generic competencies does neither. It includes everyone who can read and excludes nobody.
What actually works: specific, concrete requirements that reflect what the role genuinely demands. Not "experience in a fast-paced environment" but "comfortable managing three to five client relationships simultaneously with competing deadlines." Not "strong communication skills" but "able to explain technical product changes to non-technical stakeholders clearly and without condescension." Specificity filters. Generality doesn't.
The Lack of Salary Transparency
Candidates filter by salary before they read anything else on most job boards.
A job ad with no salary, or a salary range so wide it communicates nothing, loses a significant proportion of its target audience before they reach the job title. The candidate at the top of the range assumes it's below them. The candidate at the right level isn't sure it's worth their time to find out. The only candidates who consistently apply to ads without salary information are those with fewer alternatives, which is not the pool you were hoping to fish in.
The reluctance to include salary is understandable in theory. You don't want to anchor too low. You don't want existing employees to make comparisons. You don't want competitors to know your budget.
None of those concerns outweigh the cost of filtering out the candidates you actually want. The market already knows roughly what the role should pay. Tools like LinkedIn Salary, Glassdoor, and Totaljobs Salary Checker mean that candidates have access to benchmarking data whether you include a number or not. The only person who doesn't know what you're offering is the candidate reading your ad.
Include a salary range. Make it honest. The candidates who would have applied at the top end of a realistic range and been disappointed by the actual offer are not candidates you were going to place anyway.
You're Writing for Everyone and Reaching Nobody
Generic job ads attract generic applicants.
An ad written to appeal to the broadest possible pool of candidates tends to produce the broadest possible pool of candidates, most of whom are not right for the role. This feels counterintuitive. More applications should mean better odds. In practice it means more screening time, more unsuitable conversations, more time between posting and placement, and a hiring process that exhausts the team before the right person appears.
The ad that says "we're looking for an ambitious, driven, results-focused individual who thrives in a fast-paced environment" is describing a demographic that includes roughly 800,000 people currently browsing job boards. The ad that says "we're looking for someone who has rebuilt a customer success function before, is comfortable with the ambiguity of a Series A business, and wants to own a team within eighteen months" is describing maybe two hundred people and most of them will be the right person.
Writing for a specific person means accepting that the ad will put some candidates off. It is the ad working correctly.
The Culture Section that Isn't Believable
"We're a passionate team of innovators who work hard and play hard, with a culture built on trust, collaboration, and continuous learning."
Every company says this. Every single one. Including the ones where the culture is none of those things. Candidates have read this paragraph approximately a thousand times and have learned to skip it entirely.
Culture copy that is generic is worse than no culture copy at all because it takes up space, adds nothing, and signals that nobody thought carefully about what to write. The candidate's reaction is not "this sounds like a great culture" but "everyone says this."
What actually signals culture is specificity. Not what you value but how those values appear in practice. Not "we believe in work-life balance" but "our engineering team doesn't do on-call rotations and hasn't shipped a weekend release in two years." Not "we invest in our people" but "everyone gets a personal learning budget and four days a year to use it." Details that could only be true of your organisation, not of every organisation.
If you can't write something specific about your culture, that is useful information about whether you have a culture worth advertising.
The Qualifications that Usually Aren't Required
Degree requirements for roles that don't functionally require a degree. Five years of experience for a mid-level role. A specific software tool listed as essential when it's actually learnable in a week. These requirements filter out candidates who could do the job and attract candidates who have checked the boxes without necessarily being able to do it.
Requirement inflation happens for understandable reasons. Someone writes a requirement into the template and it never gets removed. The hiring manager adds things they'd like rather than things they need. HR adds degree requirements because it feels like quality assurance.
The practical effect is a narrower candidate pool, a less diverse applicant group, and the exclusion of people who would have been excellent hires. Each unnecessary requirement costs you candidates who were right but didn't quite fit the description.
Before every requirement on the list: ask whether a candidate without this could learn it within three months in the role. If yes, make it a preference, not a requirement. The list of actual requirements for most roles is considerably shorter than the list that appears in most job ads.
How SquareLogik Approaches Job Ad Quality
We work on the brief before we work on the sourcing. Part of that is making sure the external communication about the role is actually doing what it needs to do.
An ad that filters out the right candidates before they apply makes the sourcing harder, the pipeline thinner, and the eventual placement less likely to be the strongest available person. Fixing the ad is often faster and cheaper than intensifying the sourcing effort.
If your current job ads are producing too many wrong-fit applications or not enough right-fit ones, the copy is usually where the problem starts. We are happy to look at what you are currently running and tell you honestly what is likely to be causing it.
Frequently Asked Questions
Why are my job ads not attracting the right candidates?
Usually one of four reasons: the ad is written as a job description rather than a candidate-facing communication, the requirements are generic rather than specific enough to filter effectively, salary is absent or too vague to be useful, or the culture and opportunity are described in language every employer uses rather than language specific to your organisation. The ad that reaches the right person needs to be specific enough that they recognise themselves in it and clear enough about the opportunity that they know why it is worth pursuing.
What is the difference between a job description and a job ad?
A job description is an internal document describing the scope and requirements of a role from the employer's perspective. A job ad is an external communication aimed at persuading a specific type of candidate that the role is worth their attention. Most organisations post their job description as a job ad and are surprised when it underperforms. A job ad should describe what the candidate will do, what they will gain, and why this opportunity is worth considering over the alternatives they have access to.
Should I include salary in a job ad?
Yes. Candidates filter by salary before reading anything else on most job boards. An ad without salary, or with a range so wide it signals nothing, loses a significant proportion of the right audience before they reach the job title. The concern about anchoring too low or triggering internal comparisons does not outweigh the cost of filtering out candidates who would have been right for the role. The market already has access to salary benchmarking data. The only person who does not know what you are offering is the candidate reading your ad.
How specific should a job ad be?
Specific enough that the right candidate recognises themselves in it and the wrong candidate self-selects out. Generic requirements like "excellent communication skills" and "ability to work independently and as part of a team" include everyone and filter nobody. Specific requirements and a specific description of the work attract a smaller, more relevant pool and produce a better quality pipeline than a broad ad generating high application volume from the wrong people.
What should the culture section of a job ad include?
Specific, concrete details that could only be true of your organisation rather than generic statements every employer makes. Not "we believe in work-life balance" but the specific practice that demonstrates it. Not "we invest in our people" but the actual investment: a learning budget figure, days allocated to development, a promotion that happened recently. Generic culture copy signals that nobody thought carefully about what to write. Specific details signal that the culture is real enough to describe.
How do unnecessary qualification requirements affect job ad performance?
They narrow the candidate pool, reduce diversity, and exclude people who could do the job well. Degree requirements for roles that do not need degrees, experience thresholds set above what the role requires, and specific tools listed as essential when they are learnable on the job all filter out candidates who would have been strong hires. Before each requirement, ask whether a candidate without it could learn it within three months in the role. If yes, it should be a preference rather than a requirement.
How to Build a Talent Pipeline Before You Need It
Reactive hiring is expensive and slow. Building a talent pipeline before you need it changes the cost, speed, and quality of every hire that follows. Here's how to do it properly.
Here is how reactive hiring works.
A role opens. Everyone agrees it needs to be filled quickly. A job ad goes up. Applications come in over two weeks. The recruiter spends another week screening. Interviews happen in week four. A decision is made in week six. The preferred candidate is working three months' notice. Someone starts in week eighteen.
By which point the team has absorbed the workload for four months, the manager has had three awkward conversations with the finance director, and the person who eventually starts is the best of whoever happened to apply to that specific job ad during that specific two-week window — which is a much smaller pool than the full available talent in the market.
This is not a process problem. It is a timing problem. You started too late.
The organisations that hire best aren't better at moving faster once a vacancy opens. They're better at having relationships in place before it does. That's what a talent pipeline actually is — and it is considerably more useful than the definition most people give it.
What a Talent Pipeline Is (And Isn't)
A talent pipeline is not a database of CVs collected from previous applications and left to go cold.
That is a talent archive. It sits there, dating itself, until someone searches it desperately during a vacancy and discovers that half the people in it moved on two years ago and the other half applied for something completely different.
A genuine talent pipeline is a set of active, maintained relationships with people who might be right for future roles — people who know your organisation, who have some level of existing engagement with you, and who, when the right role opens, are already warm enough to have a real conversation rather than receiving a cold approach from a stranger.
The distinction matters because the value of a pipeline is entirely in the warmth of the relationships within it. A list of names is not a pipeline. A list of names attached to a history of meaningful touchpoints, a clear sense of mutual interest, and some degree of established trust — that is a pipeline.
Building one requires deliberate effort over time. It also produces returns that compound. Every relationship built before a vacancy opens is a vacancy that costs less to fill, takes less time, and produces a stronger shortlist than starting from scratch.
Which Roles Actually Need a Pipeline
Not every role justifies proactive pipelining. The effort required is real, and spreading it across every position on the org chart is a reliable way to do none of it well.
Prioritise roles with any of the following characteristics.
They're hard to fill when vacant.
If a role has taken three months or more to fill in the past, or if the candidate pool is genuinely scarce, a pipeline is not a nice-to-have — it's the difference between a structured search and a crisis scramble. Specialist technical roles, registered managers in care, senior commercial appointments, niche engineering disciplines — these are exactly the roles that benefit most from having warm relationships in place before the vacancy opens.
They're business-critical.
A vacancy in a role that directly affects revenue, patient safety, client relationships, or operational continuity is expensive every day it remains open. Knowing who you'd call first if that role became vacant is basic risk management.
They're high-turnover.
Roles that cycle regularly — not because of organisational failure but because of sector norms, role design, or natural career progression — benefit from a perpetually warm pipeline rather than a perpetual reactive search.
They're senior.
Senior and executive roles take the longest to fill from a standing start and are the most damaged by the pressure to fill quickly. A maintained pipeline of senior relationships allows a search to begin from a position of intelligence rather than a position of urgency.
Identify your top five to ten priority pipeline roles. Focus the effort there first.
How to Source Proactively: Finding the Right People Before the Job Exists
Proactive sourcing — finding and engaging potential candidates before a vacancy is open — is the foundation of a talent pipeline. It is also the part most organisations treat as optional until they're in trouble.
The starting point is knowing who the right people are. For most roles, this means identifying individuals currently in comparable positions at comparable organisations — people who are demonstrably doing the job you'll eventually need to fill, and doing it well enough that they haven't obviously needed to move.
This market mapping can be done manually for a handful of roles or with AI-assisted tools for broader coverage. The output should be a prioritised list of people worth building a relationship with — not a mass outreach list, but a targeted group of individuals where the effort of engagement is proportionate to the value of the relationship.
Initial outreach should not mention a vacancy, because there isn't one. It should be genuine, specific, and low-pressure: an industry observation, a piece of relevant content, a shared connection who made an introduction. The goal is not to recruit — it is to begin a relationship that might eventually be relevant. This requires patience and a recruiter who understands that forcing the timeline undermines the whole approach.
Employee referrals are one of the most underused proactive sourcing channels. Your current high performers know who the other high performers in their field are. A structured referral scheme with a meaningful incentive and a clear, simple process for making introductions builds pipeline from warm intelligence rather than cold database searching.
Professional communities, events, and networks are also genuinely productive for specific disciplines. Being present in the spaces where your target candidates spend their time — industry conferences, professional associations, online communities — creates organic relationship opportunities that cold outreach doesn't replicate.

Nurturing the Pipeline: Staying Relevant Without Being Annoying
This is the part that defeats most organisations. They build a list, make initial contact, and then go quiet until a vacancy opens — at which point they reach out again, months later, asking for something.
That is not a pipeline. That is a list of people you occasionally contact when you need something.
Maintaining genuine pipeline relationships requires a different cadence. Not relentless contact — that tips into harassment — but consistent, low-pressure, value-adding touchpoints over time.
Sharing relevant industry content with a brief, genuine observation. Congratulating someone on a career milestone or a piece of published work. Making an introduction to someone they should know. Inviting them to something genuinely relevant — a roundtable, a webinar, a conversation — rather than a thinly veiled recruitment pitch.
The standard to hold this to is simple: would this contact make sense even if you never had a vacancy? If the answer is yes, it's a relationship. If the answer is only makes sense when you need something, it's still a list.
CRM systems — whether a specialist recruitment CRM or a well-maintained spreadsheet — are necessary for managing this at any real scale. Recording what you know about each person, what the last interaction was, what their career situation appears to be, and when it makes sense to reach out again prevents the pipeline from becoming an archive.
The Internal Pipeline: Succession and Development
Talent pipelining doesn't only apply to external candidates. The most immediately actionable pipeline for many organisations is internal.
Identifying which current employees could, with development, step into more senior or specialist roles — and then actively developing them toward that readiness — is a form of pipelining that costs less, produces faster time-to-productivity, and retains institutional knowledge that an external hire never has.
Succession planning for critical roles doesn't require a formal HR programme with documentation that nobody reads. It requires answering one question for each business-critical position: if this role became vacant tomorrow, who internally would be closest to ready, and what would they need to be genuinely ready within six to twelve months?
Answering that question honestly, and then investing in closing the gap, is proactive talent management in its most practical form. It also reduces external hiring pressure — which is the point.
Employer Brand as a Pipeline Tool
The organisations with the warmest talent pipelines are usually the ones where candidates already want to work before being approached.
Employer brand — the reputation an organisation has in its relevant talent market — is a passive pipeline mechanism that works at scale. A company with a strong employer brand in its sector has potential candidates who are already familiar with it, already positively disposed toward it, and already more likely to respond to a thoughtful approach.
Building employer brand for pipeline purposes means being visible in the places your target candidates spend time. Engineering teams blogging about interesting technical problems. Leaders speaking at industry events. Consistent, authentic content about the culture, the work, and the people — not a careers page written by marketing, but evidence of what it actually looks and feels like to work there.
This is a long-term investment with compounding returns. The candidate who follows your company's content for a year before being approached is a warm conversation. The candidate cold-approached without any prior awareness is starting from zero.
How to Know Whether the Pipeline Is Working
A talent pipeline that nobody measures is a pipeline that gradually becomes an archive without anyone noticing.
The metrics worth tracking are not complicated. When a vacancy opens for a priority role, what proportion of the shortlist comes from pipeline relationships rather than new sourcing? How long does it take to get to a first interview from vacancy opening for pipeline-supported roles versus non-pipeline roles? What is the offer acceptance rate for candidates sourced from the pipeline versus those sourced reactively?
If the pipeline is working, time-to-hire for priority roles should be shorter, quality of shortlist should be higher, and the cost of reactive sourcing for those roles should be falling. If those metrics are not moving, the pipeline is a list.
The feedback loop matters. A pipeline that is regularly reviewed — which relationships are warm, which have gone cold, which roles need new relationship-building effort — stays useful. One that is built once and then left runs down within twelve months as people move, change priorities, and forget who you are.

For roles where we know a client's hiring needs are recurring or where the candidate pool is scarce enough to justify proactive maintenance, we build and nurture candidate relationships between searches rather than starting from scratch each time. When a vacancy opens, the first call goes to people who already know us, know the client, and have some existing level of interest — which compresses the search and produces a better quality conversation.
We also use AI to extend the mapping and identification phase — finding the right people faster, tracking market movements, and surfacing candidates whose situation may have recently changed in ways that make them newly open to a conversation.
If you're looking to move from reactive to proactive hiring for your priority roles, the conversation about what a talent pipeline strategy looks like for your specific situation is worth having before the next vacancy opens.
Frequently Asked Questions
What is a talent pipeline?
A talent pipeline is a set of active, maintained relationships with people who might be right for future roles — before those roles are open. It is not a database of CVs from previous applications. The value of a pipeline is entirely in the warmth and relevance of the relationships within it. A pipeline means that when a vacancy opens, you already have people to call who know you, have some existing engagement with your organisation, and are warm enough for a real conversation rather than a cold approach.
Which roles should you build a talent pipeline for?
Prioritise roles that are hard to fill when vacant, business-critical, high-turnover, or senior. These are the roles where reactive hiring is most expensive, most damaging, and most likely to result in a pressured appointment that doesn't hold. For broadly available roles with large active candidate pools, the investment in proactive pipelining rarely justifies the effort. Focus pipeline effort where the cost of a vacancy and the difficulty of filling it quickly is highest.
How do you proactively source candidates for a talent pipeline?
Market mapping — identifying people currently doing comparable roles at comparable organisations — is the foundation. Employee referrals from current high performers are consistently the warmest and most productive source. Professional communities, industry events, and networks create organic relationship opportunities. AI-assisted sourcing tools can extend this mapping significantly for broader or more complex pipelines. Initial outreach should not lead with a vacancy — it should be genuine, low-pressure, and add some value independent of whether a role ever materialises.
How do you maintain candidate relationships in a talent pipeline?
With consistent, low-pressure, value-adding contact over time — not relentless outreach. Sharing relevant content with a genuine observation, congratulating someone on a career milestone, making a relevant introduction, inviting them to something genuinely useful. The test is whether the contact would make sense even if you never had a vacancy. A CRM system is necessary for managing this at scale — recording interaction history, current status, and when the next touchpoint makes sense.
How long does it take to build a talent pipeline?
Meaningful pipeline relationships typically take six to eighteen months to develop to the point where they meaningfully accelerate a search. This is why the best time to build a pipeline for a critical role is before there's any urgency. Organisations that start pipelining only when a vacancy opens are still starting too late — they're just starting slightly earlier in the reactive cycle. The compounding returns of an established pipeline are most visible twelve to twenty-four months after the investment begins.
How does a talent pipeline reduce recruitment costs?
A warm pipeline reduces cost per hire in several ways: less time spent on active sourcing, shorter time-to-hire reducing vacancy costs, higher offer acceptance rates from candidates who already know the organisation, and lower agency dependency for priority roles. Reactive sourcing for a scarce-candidate role from a cold standing start is consistently the most expensive recruitment model. A maintained pipeline converts that cold start into a warm conversation — which reduces every downstream cost in the process.
