After reviewing thousands of resumes, certain mistakes appear over and over — and most of them are invisible to the person who wrote the resume. Here are the seven things that make experienced recruiters cringe, and exactly how to fix each one.
1. Responsibilities instead of achievements
"Responsible for managing social media accounts." Every candidate says this. None of it differentiates you. Recruiters want to know what happened as a result of your work:
- Before: Responsible for managing social media accounts
- After: Grew Instagram following from 4k to 22k in 8 months by launching a weekly video series that averaged 40k views
The fix: every bullet starts with a past-tense action verb and ends with a number or measurable outcome.
2. "Passionate", "driven", "results-oriented"
These words have appeared on so many resumes that they communicate nothing. Recruiters skim past them instantly. If you're passionate about something, prove it with an achievement — don't claim it.
3. Two-column layout
Looks great as a PDF. Gets completely garbled by ATS parsing software, which reads documents as a single left-to-right text stream. Content from column 2 ends up jumbled mid-sentence inside content from column 1. Use a single-column format for any role where you apply via an online portal.
4. Generic summary (or no summary)
"Experienced professional with a strong background in cross-functional environments." This tells a recruiter nothing they can act on. Your summary should name the role you're targeting and your strongest qualifier in the first sentence — that's it. If you can't summarize your value proposition in two sentences, your resume has a positioning problem.
5. Dates that don't add up
Overlapping dates, gaps with no explanation, or roles that ended before they started (typos happen) all raise immediate red flags. Go through your dates carefully. For any gap over 3 months, add a one-line explanation: "Career break for family care, followed by [certification]."
6. Skills listed as progress bars or ratings
"JavaScript ████░░ 4/5 stars." What does 4/5 mean? That you know 80% of JavaScript? It has no meaning to a recruiter and is actively distracting. List skills plainly. If seniority matters, use categories: "Proficient: Python, SQL" and "Familiar with: Rust, Go."
7. One resume for every job
Sending the same resume to every posting is the single highest-impact mistake. ATS systems score you against a specific job description. A resume that matches 85% of one posting might match 40% of a similar-sounding role at another company. Spend 10 minutes tailoring the summary and keywords for every application that matters to you.
