Most CVs are rejected in seconds. A recruiter skims dozens at a time, and screening software filters many before a human ever sees them, so a strong candidate with a weak CV loses out to a weaker candidate who presents better on paper. The good news is that the mistakes that cost people interviews are common, predictable and fixable. Correct them and you dramatically improve your odds of getting to the interview, where you can actually sell yourself.

This guide runs through the CV mistakes that quietly kill applications, and how to fix each one. It is written for UK job seekers who want their CV to open doors rather than close them.

Mistake 1: Too Long and Too Dense

Two pages is the standard in the UK for most roles, and one page is fine early in a career. A three or four page CV signals that you cannot prioritise, and a wall of tiny text will not be read. Cut ruthlessly: keep what is relevant to this job, use clear headings and white space, and make the important things easy to find in a ten-second skim.

Mistake 2: A Generic CV Sent to Every Job

The single most common mistake is sending the same CV to every role. Employers can tell instantly, and screening software is looking for the language of the specific job. Tailor your CV to each application: mirror the key skills and terms from the job description, lead with the experience that matters most for that role, and cut what is not relevant.

Mistake 3: Listing Duties Instead of Achievements

A CV that lists what you were responsible for tells the reader nothing about how good you were. Anyone in your role had those duties. Instead, show results: what you improved, delivered, saved or grew, with numbers wherever you can. Achievements with evidence are what make a reader stop and want to meet you.

Mistake 4: A Weak or Waffly Personal Profile

The short profile at the top is prime space, and most people waste it on empty phrases like hard-working team player seeking a challenging role. Use those few lines to say who you are professionally, your key strengths, and what you offer this employer, in specific terms. If it could describe anyone, rewrite it.

Mistake 5: Typos and Careless Errors

A single obvious typo can end an application, because it reads as carelessness. Spelling mistakes, inconsistent dates, the wrong company name left in from a previous application: all are avoidable and all do damage. Proofread slowly, read it aloud, and get a second person to check it before you send.

Mistake 6: Formatting That Breaks Screening Software

Many CVs are first read by applicant tracking software, and fancy templates full of tables, columns, text boxes, graphics and unusual fonts can be scrambled or ignored by it. Keep the layout clean and simple, use standard headings, save in the format the employer asks for, and avoid burying key information inside images or headers the software cannot read.

Mistake 7: Unexplained Gaps and Muddled Order

List your experience in reverse date order, most recent first, and account for significant gaps briefly and honestly rather than leaving a mysterious hole. A short, matter-of-fact note about a gap is far better than leaving the reader to guess, which they will rarely do in your favour.

Mistake 8: Irrelevant and Outdated Detail

Your CV is not your life story. Drop the school grades once you have a degree and experience, cut jobs from decades ago down to a line, and leave off a photo, date of birth, marital status and a long list of generic hobbies. Every line should earn its place by helping you get this job.

Mistake 9: No Keywords for the Screening Stage

Because software often screens first, a CV that does not contain the terms an employer is searching for may never reach a person. Read the job description carefully and make sure the genuine skills, tools and qualifications you have are named clearly on your CV, in plain language, exactly as the employer refers to them.

Mistake 10: Stretching the Truth

Exaggerating a role, inflating a grade or claiming a skill you do not have is a serious risk. It tends to surface at interview or in references, and it can cost you the job or worse. Present your genuine experience in the strongest honest light instead, which is almost always more than enough.

How to Fix Your CV

The Bottom Line

The CV that wins interviews is rarely the flashiest. It is the one that is clear, tailored, honest and easy to read in seconds, that leads with achievements and speaks the language of the specific job. Fix these common mistakes and you stop losing to weaker candidates who simply present themselves better on paper.
