Not finding qualified candidates? Check these five things before you look elsewhere

When a job attracts plenty of applicants but none seem qualified, or attracts almost nobody, the instinct is to post in more places. Check your own process first. Qualified people are often put off by the posting or filtered out by the screen, and fixing either costs nothing. Then add sources deliberately: referrals work well but narrow your pool, and your own past applicants are the most overlooked source of all.

First, which problem do you have?

What you’re seeing	Likely cause	Start with
Lots of applicants, almost none qualified	The posting attracts everyone, or your screen is too strict	Checks 1, 2 and 5
Few applicants at all	The posting isn’t reaching people, or isn’t convincing them	Checks 3 and 4, then sources
Qualified applicants who drop out or decline	Pay, speed, or how they’re treated in the process	Check 4
Good applicants, but you “can’t decide”	The requirements aren’t written as evidence	Check 1

Check 1: Are your must-haves real?

A long list of must-haves doesn’t just filter applicants; it can filter out the right ones. In a 2021 survey by Harvard Business School and Accenture, most employers using recruiting software relied on it to filter or rank applicants, and of those, 88% said their process screened out qualified high-skills candidates at least some of the time because they didn’t exactly match the job description (Hidden Workers).

Cut the list to the three to five things the person genuinely needs on day one, and write each as evidence you could see. Our guide to must-haves and nice-to-haves has a test for every requirement and a free worksheet.

Check 2: Is your screen throwing away people who qualify?

Before deciding the pool is weak, re-read a sample of the applications you turned down. Pick ten at random and read each one against your requirements again, slowly. If two or three of them actually meet your must-haves, the problem isn’t the market. It’s usually one of these:

• A requirement read too literally (“5 years” when they had four and a half).
• Evidence described in different words from your posting.
• A gap in work history treated as a no. Almost half the companies in the same Harvard study filtered out resumes with gaps of more than six months, regardless of other qualifications.
• “Not mentioned” treated as “doesn’t have”. It should be unclear, and worth a question.

Our screening guide explains how to audit the rejected pile properly.

Check 3: Does the posting give people a reason to apply?

Qualified people with jobs read postings critically. A posting that is mostly a list of demands and adjectives gives them little to go on. Make sure it says:

• What the work actually is, in the first few lines, in plain words.
• The pay range. Many places now require it, and a posting without one asks people to apply without knowing whether the job is viable for them.
• That the job is real and current, and when you expect to decide. Many applicants now suspect postings are fake; our article on ghost jobs explains why, and what to say.
• What happens after they apply.

Check 4: Are you losing people after they apply?

If qualified applicants appear but disappear, look at what happens to them. How many days pass between their application and your first contact? Between the final interview and an offer? Every day an applicant waits is a day another employer can make them an offer. Our applicant tracker has a “days waiting” column for exactly this, and our article on hiring metrics shows how to measure time to hire.

Check 5: Are you screening for the job, or for a profile?

“Qualified” sometimes quietly means “looks like the last person in the role”: the same industry, the same kind of employer, the same career path. If you’re rejecting people who could clearly do the work because their background is unfamiliar, the shortage is partly of your own making. Our article on skills-based hiring covers how to judge the work rather than the path.

Then, where to look

Referrals: strong, with one big caveat

The best large-scale evidence on referrals comes from Burks, Cowgill, Hoffman and Housman (2015), who studied personnel data from nine large firms in call centres, trucking and high-tech. Referred applicants were more likely to be hired and to accept offers, though their skill characteristics were similar to other applicants’. Once hired, they were substantially less likely to quit and performed similarly on most measures, with fewer accidents in trucking and more patents in high-tech.

The caveat: people tend to refer people like themselves. The U.S. EEOC’s guidance notes that word-of-mouth recruiting can promote diversity in a diverse workforce, but that in a workforce that isn’t diverse, relying on it is a barrier to equal opportunity if it doesn’t produce an applicant pool that reflects the qualified labour market (EEOC Compliance Manual, Section 15). Use referrals as one source among several, not the only one, and screen referred applicants against the same requirements as everyone else.

Your own past applicants

People who applied for a similar role before, and were close, are already interested in working for you. If you kept their details (with their consent and within your retention rules), a short, personal note when a new role opens costs nothing.

Your own careers page

A page on your own website listing your open jobs lets people find you, and lets applicants confirm a posting is genuinely yours.

Specialist and local channels

Where qualified people for this job already gather: the professional body’s job board for a licensed profession, a college programme that trains people for the role, an industry association, a trade or community organisation. These reach fewer people than a general job board, but a larger share of them may have what you need.

General job boards

Useful for reach. Expect volume, and plan to screen it.

Where SortTheStack fits

SortTheStack helps with checks 1 and 2: it drafts requirements from your job description for you to edit, reads every application against them, and marks missing evidence as unclear rather than as a rejection. Each job gets a public careers page, and on the Practice and Group plans it can match past applicants to new roles. It doesn’t post to job boards. See how the screening works.
