7 Job Description Mistakes That Are Costing You Top Candidates

Most hiring problems start before the first resume arrives. The job description is the front door to your hiring process. If it's broken, everything downstream suffers. You get the wrong applicants, not enough applicants, or great candidates who take one look and move on.

These are the seven mistakes that show up most often, and what to do instead.

Mistake 1: Requirements Lists That Read Like a Wish List

The average job description lists 14 requirements. Research suggests most roles actually need 5-8 to be done well.

The difference matters: every extra requirement reduces your applicant pool. Some estimates put it at 10-15% fewer applicants per unnecessary requirement. And because over-specified requirements affect different demographic groups differently. Women are significantly more likely to self-select out of roles where they don't meet every listed qualification, and bloated requirements lists have an outsized impact on candidate diversity.

The test: for each requirement on your list, ask "Would someone who doesn't have this be unable to do the job?" If the honest answer is no, move it to a "preferred" list or cut it entirely.

Separating must-have requirements from nice-to-haves has been shown to increase female applicants by 20%+, one of the highest-return, lowest-effort changes you can make.

Mistake 2: No Salary Range

This one is simple and still pervasive.

Job postings that include salary ranges receive 30% or more additional applications than those that don't, based on data from LinkedIn and Indeed. The logic isn't complicated: candidates have a number in mind. If you don't give them yours, they assume the worst, or they waste everyone's time applying for a role that's $30K below their expectation.

Pay transparency legislation is expanding rapidly across US states. In many jurisdictions, publishing a range is now legally required. Even where it isn't, candidates expect it. The companies that still hide compensation are signaling something, and it's not what they think they're signaling.

Post a real range. Not "$80K-$160K" (that's not a range, it's an avoidance). A tight range like $95K-$110K tells a candidate where they stand. It filters in the right people and filters out mismatches before either side wastes time on a call.

Mistake 3: Gendered Language

Language bias in job descriptions is well-documented. Words like "rockstar," "ninja," "dominant," "aggressive," "competitive," and "assertive" skew male in research on candidate perception, leading to fewer female applicants. Words like "collaborative," "supportive," and "nurturing" skew female.

The kicker: most teams don't notice this because they're copying from old descriptions or competitor postings that have the same problem.

Research in the Journal of Personality and Social Psychology established the mechanism clearly: gendered wording in job ads predicts who applies. The effect holds up in replicated research. It's not hypothetical.

Run your description through a bias checker before posting. HireScore does this automatically. If you're doing it manually, at minimum audit for the obvious culprits: the "ninja/rockstar/wizard" language and the "aggressive/dominant" descriptors. Replace them with neutral equivalents that describe the actual behavior you want.

Mistake 4: A Wall of Text

Candidates are scanning, not reading. Most spend under 30 seconds on a job description before deciding whether to apply.

What they're doing in those 30 seconds: looking for the title, the comp, the location, the key responsibilities, and the main requirements. If your description is structured as five dense paragraphs with no headers and no bullets, they can't find any of that. They move on.

Format as if the reader is in a hurry (they are):

• Short sections with clear headers
• Bullet points for responsibilities and requirements
• Compensation called out prominently, not buried at the bottom
• Under 700 words total (Indeed's data shows postings under 700 words get more applications per view)

Nobody has ever complained that a job description was too easy to read.

Mistake 5: No Sell. You Forgot to Make the Case for Applying.

The best candidates have options. They're not applying to everything they see. They're evaluating opportunities. Your job description needs to answer the question every qualified candidate is asking: Why should I apply here instead of the three other roles in my inbox?

Most job descriptions never answer this question. They list what the company needs. They don't explain what the candidate gets.

"What's in it for me" for a strong candidate includes:

• The problem or challenge: What makes this role intellectually interesting or impactful?
• The team: Who are they working with? What's the tenure, caliber, culture?
• The trajectory: Where does this role lead? What's the growth path?
• The company's position: Traction, revenue, customers, stage. Whatever signals that the company is worth betting on.

Three sentences of specific, honest sell beats three paragraphs of "we're a mission-driven team that values innovation." Specificity is the differentiator.

Mistake 6: Copying Competitors

This is more common than most teams realize. Someone is hiring for a role they haven't hired for before. They Google the title, find a few postings from similar companies, and use them as a template.

The problem is that those postings are probably also copied from someone else, carrying forward the same mistakes, the same inflated requirements, the same vague language. You inherit all the problems and none of the differentiation.

Competitor postings are useful for one thing: benchmarking the title and general scope. They're not a substitute for understanding what your version of this role actually requires, what your team's culture actually is, and what makes your opportunity worth a great candidate's attention.

Write from your reality, not someone else's template.

Mistake 7: Ignoring ATS Optimization

A well-written job description that can't be parsed by applicant tracking systems, or that can't be found by job board algorithms, fails before a human sees it.

Most job boards rank postings based on relevance signals. Your job title, key terms, and structure affect visibility. Common ATS problems in job descriptions:

• Non-standard formatting: PDFs, unusual characters, and heavy formatting can confuse ATS parsers. Use clean text.
• Keyword gaps: If a candidate searches "data analyst" and your posting says "data insights professional," you don't match. Use the terms candidates actually search for.
• No clear sections: Many ATS systems try to extract responsibilities, requirements, and benefits into separate fields. If your description doesn't have these clearly delineated, the extraction fails and the posting loses quality signals.

This doesn't mean stuffing keywords awkwardly into the text. It means using standard, plain language for role titles and skills, and structuring the posting with clear, labeled sections.

The Pattern Behind All Seven Mistakes

Every mistake on this list comes from the same root cause: job descriptions are written fast, reactively, without a process, and with no feedback loop on what's working.

The fix isn't complicated. It's a consistent process: define the role before you write it, lead with the opportunity, be specific and honest about requirements, include compensation, check your language, and format for scanners.

That process takes time. For every role. Every time.
