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 you apply for is one of the biggest mistakes a job seeker can make. A generic CV does not address the specific requirements, language, or priorities of any individual role — and both recruiters and ATS systems will notice. 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. The summary is the first paragraph a recruiter reads — it sets the tone for your entire application. 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. Be specific and quantify where possible.

Mistake 3: Listing Duties Instead of Achievements

Saying "Responsible for managing the marketing team" tells the recruiter nothing about your impact or effectiveness. It is what your job description said — not evidence of what you actually accomplished. Fix: Use the CAR framework: Context, Action, Result. For every bullet point, describe what you did and what measurable result it produced. Example: "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

Many visually appealing CV templates are actually terrible for ATS systems. Features like tables, text boxes, columns, graphics, headers and footers, 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

ATS systems filter CVs based on keywords that match the job description. If your CV is missing the specific technical terms, tools, and role-relevant language that a hiring system is configured to look for, it may be filtered out regardless of how experienced you are. Fix: Read each job description carefully and identify the key skills and terminology it emphasizes. Include those terms 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 — one of the last qualities any employer wants to associate with a candidate. Research consistently shows that recruiters list spelling mistakes as a top reason for immediately rejecting a CV. Fix: Use spell check, read your CV out loud, use Grammarly, and ideally ask a second person to proofread it before submission.

Mistake 7: Including Irrelevant Personal Information

Including your date of birth, marital status, nationality, religion, or a photograph is considered outdated in the UK and most Western countries. Not only is this information irrelevant to your professional qualifications, it can also introduce unconscious bias into the hiring process. Fix: Your CV should include only your name, professional contact details (email, phone, city, LinkedIn), and a portfolio link if relevant to your field.

Mistake 8: CV Is Too Long

Unless you are applying for an academic position or a very senior executive role, your CV should be no more than two pages. A CV that runs to four or five pages suggests poor editing judgment. Fix: Focus on the last ten to fifteen years of experience. Remove early-career roles that are no longer relevant. Cut redundant bullet points. If information does not directly support your candidacy, remove it.

Mistake 9: Unexplained Employment Gaps

Unexplained gaps in your work history are a red flag for many recruiters. While career breaks are perfectly normal, leaving unexplained blanks makes recruiters fill the gaps with their own assumptions. Fix: Briefly account for any gaps of three months or more. If you were studying, freelancing, caregiving, volunteering, or upskilling during that period, note it clearly.

Mistake 10: No Quantification of Achievements

Vague achievements like "improved team performance" or "contributed to company growth" are meaningless without context. Every recruiter reads these phrases hundreds of times per week. 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? Quantified achievements are specific, credible, and memorable.

Mistake 11: Using Passive Language

Writing "was responsible for" or "assisted with" 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. These words position you as someone who drives results.

Mistake 12: Inconsistent Formatting

Inconsistent date formats, varying font sizes, mixed bullet styles, and uneven spacing 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, and ensure consistent spacing between sections.

Mistake 13: Unprofessional Email Address

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

Mistake 14: Unprofessional File Name

Submitting a file named "cv final FINAL v3 use this one.pdf" signals disorganization. Fix: Name your CV professionally: "JohnSmith_CV_2026.pdf". This is clean, professional, and easy to find in a recruiter's download folder.

Mistake 15: Not Checking ATS Compatibility Before Submitting

Many applicants spend hours perfecting their CV for human readers and then send it straight to an employer without ever checking how it will perform against automated screening. Fix: Before submitting your CV for any significant role, run it through ApliSense. This gives you a clear picture of your keyword alignment, structural issues, and match score against the specific role — allowing you to make targeted improvements before the real submission.
