- Mistake 1–5: the opening and structure
- Mistake 6–10: content and bullets
- Mistake 11–15: details that sink you
Most resumes aren’t rejected — they’re ignored. Small, fixable errors push yours into the “not quite” pile. Here are the fifteen we see most, each with the fix.
Mistakes 1–5: the opening and structure
1. An objective instead of a summary. “Seeking a challenging position” tells the employer nothing. Replace it with a professional summary that names the role and one proof point.
2. Contact info buried. Name, email, phone, city, LinkedIn belong in one visible header block. Recruiters won’t hunt for your phone number.
3. Multi-column or table layouts. They look fine in a PDF and break in parsers. Use the single-column rule from the ATS guide.
4. Missing or inconsistent dates. Every role needs a start and end (“Mar 2021 – Present”). Mixed formats (“2021–present” next to “03/2019 – 04/2020”) read as careless.
5. No clear target. If the reader can’t tell what role you want within five seconds, they won’t guess. Your title line or summary must state it.
Mistakes 6–10: content and bullets
6. Duty bullets instead of achievement bullets. “Responsible for the budget” vs. “Budgeted $2.4M across 6 workstreams”. Use the STAR Rewriter to convert yours.
7. No numbers. A resume without metrics is a job description. Add scale (“40k users”), money (“$1.2M saved”), time (“5 days to 2”), or percent (“+23%”) wherever true — the Quantifier writes the phrasing.
8. First-person pronouns. “I led…” weakens every bullet. Drop the “I” — “Led a team of 8…” is stronger.
9. Adjectives instead of evidence. “Detail-oriented”, “passionate”, “results-driven” carry no information. Show the result and let it prove the trait.
10. One bullet, two stories. Bullets joined by “and” are usually two achievements fighting for space. Split them.
Mistakes 11–15: details that sink you
11. Typos and grammar slips. One typo in the summary can undo everything. Read aloud, use a checker, and have a second pair of eyes — or paste the text into the Readability Checker and reread the output.
12. Skills you can’t defend. Every listed skill is fair game in the interview. Keep the list to what you could demo tomorrow (see the skills guide).
13. Wrong file name. “resume_FINAL_v3(2).pdf” signals chaos. Use FirstName_LastName_Resume_Role.pdf.
14. Photos or graphics (in most regions). In the US and much of Europe, a photo invites bias risk and adds nothing to parsing. Skip it unless local convention demands it.
15. Sending the same resume to every job. Generic resumes lose on both keyword coverage and human appeal. The 15-minute tailoring workflow in the tailoring guide fixes this for every serious application.
Fix these fifteen and your resume stops being quietly ignored. Run the Format Validator on your final version — it catches most of these mechanically in seconds.
Proofreading: finding mistakes in your own resume
Your own writing is the hardest to proofread — you read what you meant, not what you wrote. Use this checklist instead of relying on your eyes:
- Change the format. Export plain text and read the raw version — layout hides errors.
- Read bottom to top. Reversing order breaks the flow that keeps typos invisible.
- Read aloud. Stumbles and awkward tenses surface immediately.
- Check every date twice. Month-to-month consistency is the most common silent error.
- Verify contact info. One wrong digit in your phone number makes everything else pointless.
- Use a checker. The Readability Checker flags weak bullets and passive voice — then reread its output.
Mistakes by career stage
- Early career: padded bullet counts, generic objectives, missing projects or coursework that would add credibility.
- Mid-career: duty bullets instead of results, skills that can’t be defended, three-page histories that should be one or two.
- Senior: no highlights section, buried achievements, irrelevant early roles taking space from impact.
- Career change: old-field jargon with no translation, empty months unexplained, missing bridge projects.
Each stage has its own failure mode, but the fix is universal: evidence over adjectives, clarity over volume, and a reader who can tell within six seconds what you do and why it matters.
One-mistake rule: the resume audit in practice
The fastest quality gain comes from applying the “one-mistake rule”: pick the single biggest flaw in your resume — the weak summary, the duty bullets, the unreadable layout — and fix only that, tonight. Tomorrow fix the next. Most resumes are not ruined by fifteen problems; they are ruined by one dominant problem that makes every other detail invisible. The Format Validator gives you the mechanical audit (dates, sections, length, file), and the Readability Checker gives you the writing audit (bullets, weak openings, passive voice). Fix the top item in each report and re-run — two passes usually clear the list.
