The most common resume mistakes are content problems, not design ones: describing duties instead of results, sending one generic version to every job, listing skills with no evidence and burying the relevant experience. Next come layout choices that break software reading, such as columns, text boxes and images, and process errors like wrong contact details or a misnamed file. All of them are fixable in an afternoon. This guide groups twenty of them by type, with a quick fix for each.
Recruiters read a resume quickly, so a few avoidable errors can outweigh a lot of good evidence.
Content mistakes
1. Duties instead of achievements
"Responsible for managing client accounts" says the job existed. Fix: say what you did and what happened. See resume bullet points.
2. One resume for every job
A generic resume rarely shows the specific evidence a role needs. Fix: reorder and reword the top third for each application. See the targeted resume.
3. Vague summary
"Hard-working team player seeking new challenges" could describe anyone. Fix: name the role, give one fact and state the direction. See resume summary examples.
4. Skills with no evidence
A list of 30 tools with nothing to support them invites doubt. Fix: keep only what you can discuss and back each with a bullet. See the skills section.
5. No numbers or scope
Without size, frequency or outcome, a reader cannot judge the work. Fix: add scope even if you cannot add a metric. See quantifying achievements.
6. Too much old history
Fifteen-year-old jobs take space from recent evidence. Fix: shorten or remove them. See how long a resume should be.
7. Weak or missing verbs
"Helped with", "worked on" and "was involved in" hide your part. Fix: start with what you did. See action verbs.
8. Claims you cannot back up
Inflated titles or skills come out in the interview or in checks. Fix: say what you did and be ready to discuss it. See resume fraud and verification.
Layout mistakes
9. Multiple columns, text boxes and graphics
Some software reads columns line by line and scrambles the order. Fix: single column, real text. See ATS-friendly resumes.
10. Tiny fonts and tight margins
A page crammed to fit is hard to read. Fix: cut content, not margins. See fonts and margins.
11. Inconsistent formatting
Mixed date formats, bullet styles and font sizes look careless. Fix: choose one style and apply it everywhere.
12. Contact details in the header or footer
Some systems skip those areas. Fix: put them in the body of the page. See contact information.
13. Skill bars and star ratings
They are subjective and carry no information. Fix: list the skill and a short qualifier such as "daily use, five years".
14. A photo where none is expected
It can add bias or break parsing. Fix: follow local norms. See photos on resumes.
Process mistakes
15. Typos and grammar errors
Fix: read it aloud, use a spell checker, and have someone else read it. Names of employers and tools are often misspelled.
16. Wrong or unprofessional email address
Fix: use a name-based address and check the spam folder. A wrong digit in a phone number can cost an interview.
17. Generic or careless file name
"resume.docx" and "final-v7.pdf" are hard to find and look sloppy. Fix: "Firstname-Lastname-Resume.pdf". See PDF or Word.
18. Sending a scanned image
Software cannot read it. Fix: export a text PDF from the original document.
19. Not following the instructions
Posting says "include a portfolio link" or "one page only". Fix: read the whole posting and do each thing it asks. Missed instructions are an easy reason to reject.
20. Ignoring the sections that matter for this job
If the role requires a licence and the resume does not show it, a reader may move on. Fix: put requirements near the top and make them easy to find.
A short repair order
If you only have an hour, work in this order:
- Fix contact details and file name.
- Rewrite the summary and the top three bullets of the latest job for this role.
- Remove anything that does not help.
- Check layout by pasting into plain text.
- Proofread aloud and ask a friend to check.
Most of the gain comes from the first three steps. The reasons resumes get declined quickly are covered in more depth in why resumes get rejected, and the final pass is in the resume checklist.
What recruiters say they care about
When recruiters talk about what puts them off, the same themes come up: not being able to tell what the person did, signals of carelessness and obvious mismatch with the role. Beautiful design rarely saves a resume that fails on those, and plain layout rarely sinks one that succeeds. Fix content first, layout second and process last, because the first has the biggest effect and the last is the easiest.

What is the most common resume mistake?
Describing duties instead of results, so a reader cannot tell what you personally did. It is common because it is easy to write, and it is costly because it gives a reviewer nothing to score.
