15 Resume Mistakes That Cost You Interviews (2026)

Small resume mistakes compound — especially when applicant tracking systems parse your file before a human does. Here are the errors that most often kill otherwise qualified candidates.

Layout & formatting

1. Multi-column templates — parsers read left-to-right, top-to-bottom; columns scramble order. Use single-column templates.

2. Contact info in the header/footer — many parsers skip page headers. Put email and phone in the body.

3. Text inside images or icons — skills shown as graphics may not extract. Use plain text lists.

4. Tables for layout — risky for parsing. Stick to simple sections.

Content

5. No quantified achievements — "Managed projects" vs. "Delivered 12 projects on time, $2.1M budget." Numbers stand out.

6. Duty lists instead of impact — replace "Responsible for social media" with growth metrics.

7. Generic summary — "Hard-working team player" wastes space. State role, years, specialty, and one proof point.

8. Irrelevant old jobs — trim early roles to titles only or remove them.

9. Skills keyword dump — list tools you've actually used in context, not every buzzword.

ATS & tailoring

10. One resume for every job — keywords differ. Tailor summary, skills, and top bullets per posting.

11. Missing keywords from the job description — recruiters search exact phrases. Use Wizume's ATS score against the JD.

12. Wrong file type — follow instructions (PDF vs. DOCX). When unspecified, a clean PDF is safe.

Polish

13. Typos in name, company, or tools — instant credibility hit. Proofread twice.

14. Unprofessional email — use a simple first.last@gmail.com address.

15. Inconsistent dates — use the same format throughout (e.g., "Jan 2022 – Present").

Quick fix workflow

1. Run your resume through an ATS score with the target job description.
2. Compare layout to a role example.
3. Tighten the worst three bullets with strong verbs — see action verbs.
4. Export and apply.
