15 Common Resume Mistakes and How to Fix Them
Updated · 6 min read · By the CareerDesks team
Small mistakes cost interviews. Most are quick to fix once you know what to look for.
Content mistakes
- Listing duties instead of results. Fix: add what changed because of your work.
- One resume for every job. Fix: tailor each version.
- Vague summaries. Fix: name your role, specialism, and one result.
- Unexplained gaps. Fix: a one-line entry such as "Career break: caring for family" is enough.
- Irrelevant old jobs in detail. Fix: summarise roles older than 10 to 15 years.
- Exaggerated claims. Fix: only write what you can discuss in depth.
Formatting mistakes
- Text inside images or graphics. Fix: use real text so screening software can read it.
- Inconsistent dates and fonts. Fix: pick one style and apply it everywhere.
- Too long or too dense. Fix: see how long a resume should be.
- Skill bars and ratings. Fix: list skills in words, grouped by type.
- Tiny fonts and margins. Fix: keep body text at 10 to 12 points.
Sending mistakes
- Typos and wrong company names. Fix: proofread aloud and check the company name in every version.
- An unprofessional email address. Fix: use firstname.lastname or similar.
- File names like "resume-final-v3.pdf". Fix: use "Firstname-Lastname-Resume.pdf".
- Losing track of what you sent. Fix: record the version with each application in a job tracker.
