15 Common CV Mistakes That Get You Rejected (And How to Fix Them)

March 8, 2026 · 10 min read · By ApliSense Team

A single avoidable mistake on your CV can cost you an interview — even if you are perfectly qualified for the role. Recruiters process hundreds of applications and are quick to filter out CVs that show signs of carelessness, poor formatting, or misalignment with the job. The good news is that the most common CV mistakes are entirely fixable once you know what to look for.

Mistake 1: Using a Generic, One-Size-Fits-All CV

Sending the exact same CV to every job is one of the biggest mistakes a job seeker can make. Fix: Tailor your professional summary, skills section, and key bullet points for each application. Use ApliSense to analyze how well your CV matches a specific role and highlight exactly what to adjust.

Mistake 2: Weak or Missing Professional Summary

Many applicants skip the professional summary or write vague statements like "hardworking professional seeking a challenging role." These contribute nothing and set a poor tone for the entire document. Fix: Write a three to five sentence summary stating your professional identity, years of experience, top skills or achievements, and the type of role you are targeting.

Mistake 3: Listing Duties Instead of Achievements

Saying "Responsible for managing the marketing team" tells the recruiter nothing about your impact or effectiveness. Fix: Use the CAR framework: Context, Action, Result. "Led a four-person marketing team and implemented a content calendar that increased organic web traffic by 62% in six months."

Mistake 4: Poor ATS Formatting

Tables, text boxes, columns, graphics, and unusual fonts can confuse ATS parsers, causing them to misread or skip sections of your CV entirely. Fix: Use a single-column layout with clear standard section headings. Avoid tables and text boxes. Check your CV's ATS performance using ApliSense before submitting to any major employer.

Mistake 5: Missing or Misplaced Keywords

If your CV is missing the specific technical terms the ATS is looking for, it may be filtered out regardless of your experience. Fix: Read each job description carefully and include the key skills and terminology naturally throughout your CV — in your skills section, work experience descriptions, and professional summary.

Mistake 6: Spelling and Grammar Errors

A typo or grammatical error on a CV signals carelessness. Research consistently shows recruiters list spelling mistakes as a top reason for immediate rejection. Fix: Use spell check, read your CV out loud, use Grammarly, and ask a second person to proofread it before submission.

Mistake 7: Including Irrelevant Personal Information

Date of birth, marital status, nationality, religion, or a photograph are considered outdated and inappropriate in the UK and most Western countries. Fix: Include only your name, professional contact details, and a portfolio link if relevant to your field.

Mistake 8: CV Is Too Long

Unless applying for an academic position or a senior executive role, your CV should be no more than two pages. Fix: Focus on the last ten to fifteen years of experience. Remove early-career roles that are no longer relevant. Cut redundant bullet points.

Mistake 9: Unexplained Employment Gaps

Unexplained gaps in your work history are a red flag for recruiters. Fix: Briefly account for any gaps of three months or more — whether you were studying, freelancing, caregiving, volunteering, or upskilling during that period.

Mistake 10: No Quantification of Achievements

Vague achievements like "improved team performance" are meaningless without context. Fix: Add numbers wherever possible. How much did you improve performance — by what percentage, over what timeframe, with what budget, with how many team members?

Mistake 11: Using Passive Language

"Was responsible for" signals a lack of ownership and initiative. Fix: Start every bullet point with a strong action verb: Led, Built, Delivered, Increased, Reduced, Managed, Launched, Designed, Negotiated, Improved.

Mistake 12: Inconsistent Formatting

Inconsistent date formats, varying font sizes, and mixed bullet styles suggest a lack of attention to detail. Fix: Use a single font throughout, pick one date format and stick to it, use the same bullet style for all lists.

Mistake 13: Unprofessional Email Address

An email like "partyguy99@hotmail.com" immediately undermines your professional image. Fix: Create a professional email address using your name — firstname.lastname@gmail.com.

Mistake 14: Unprofessional File Name

Submitting a file named "cv final FINAL v3.pdf" signals disorganization. Fix: Name your CV professionally: "JohnSmith_CV_2026.pdf".

Mistake 15: Not Checking ATS Compatibility Before Submitting

Many applicants perfect their CV for human readers but never check automated screening performance. Fix: Run your CV through ApliSense before every significant application to get a clear picture of your keyword alignment, structural issues, and ATS compatibility score.
