Job Description Mistakes to Avoid: 10 Errors That Cost You Candidates

All resources · Job Description Mistakes to Avoid

Mistake 1: Listing too many requirements

This is the single most common and most damaging mistake. When employers list 15-20 requirements, they filter out the majority of qualified candidates. Research from LinkedIn found that women are significantly less likely to apply when they do not meet every listed requirement. The result: your talent pool shrinks to only the most confident (not necessarily most qualified) applicants. Limit requirements to 5-7 truly mandatory qualifications. Everything else belongs in "preferred qualifications." Ask yourself: "Could someone learn this in the first month on the job?" If yes, it is not a requirement.

Mistake 2: Vague, generic language

"Fast-paced environment." "Ability to multitask." "Self-starter who works well independently." These phrases appear in thousands of job descriptions and tell candidates absolutely nothing about the role. Every company thinks they are fast-paced. Every role requires some multitasking. Vague language fails to differentiate your role from the hundreds of similar postings candidates see. Replace every generic phrase with something specific to your role and company. Instead of "fast-paced environment," say "You will manage 8-10 active projects simultaneously, with 2-3 launching each month."

Mistake 3: Omitting salary information

Candidates consistently rank salary as the number one piece of information they want in a job posting. Despite this, many employers still leave compensation out. The reasons vary — fear of negotiation, internal pay ranges, or hoping to assess candidates first — but the result is the same: fewer applications, especially from senior candidates who know their market value. Many jurisdictions now legally require salary disclosure. Even where not required, including a range filters candidates with misaligned expectations and reduces time spent on offers that fall through.

Mistake 4: Writing for internal audiences, not candidates

Job descriptions written with internal jargon, company-specific acronyms, and insider context confuse outside candidates. A candidate who does not understand your internal tool names, team structures, or industry shorthand cannot assess whether they are qualified — and they will move on to a posting they do understand. Write as if the reader has never heard of your company. Define acronyms on first use. Use industry-standard terminology rather than internal labels.

Mistake 5: Making every qualification a requirement

When every qualification is listed as required, you send two messages: the bar is extremely high, and you are not thoughtful about what actually matters. Many strong candidates — particularly women and underrepresented groups — will not apply unless they meet 100% of listed requirements. Men tend to apply at around 60% match. By listing 15 requirements, you are effectively filtering for overconfident applicants rather than the most qualified ones.

Mistake 6: Focusing on what you want, not what you offer

Many job descriptions read like a list of demands: you must do this, you must have that, you must be this. But candidates are evaluating you too. The best job descriptions balance expectations with what the company provides — competitive compensation, growth opportunities, interesting challenges, team culture, and work-life balance. Candidates who feel the company values them as people, not just resources, are more likely to apply and more likely to accept offers.

Mistake 7: Using gendered or exclusionary language

Words like "ninja," "rockstar," "manpower," and "aggressive" can discourage women and non-binary candidates from applying. Research from the University of Waterloo found that certain words in job descriptions strongly correlate with the gender distribution of applicants. Use gender-neutral alternatives: "craftsperson" instead of "craftsman," "team" instead of "manpower," "ambitious" instead of "aggressive." This is not about being politically correct — it is about accessing the full talent pool.
