10 Common CV Mistakes That Cost You Interviews
Most rejected CVs are not rejected because the candidate is unqualified — they are rejected because of avoidable mistakes that make a reader stop trusting the document. Here are the ten we see most often, and the fix for each.
Mistake 1: Listing duties instead of achievements
This is the single most common CV problem and the one that costs the most interviews. A list of duties tells a recruiter what your job description said. It does not tell them what you actually contributed or what happened because you were in that role rather than someone else. Every line on a CV competes for attention; a duty wastes that attention.
The fix is to ask, for each bullet: 'What was the result of this?' or 'What changed because I did this?' Then rebuild the bullet around the answer. 'Managed the company's social media accounts' becomes 'Grew Twitter following from 2,400 to 18,000 in 12 months by introducing a weekly long-form thread format, increasing site referral traffic by 34%.' The second version is specific, verifiable, and interesting.
Not every achievement can be quantified with a number, and that is fine. 'Rewrote the internal documentation suite that had not been updated since 2018, reducing onboarding queries to the IT helpdesk by roughly half' uses an estimate and still works. What matters is that the bullet describes an outcome, not just an activity.
Mistake 2: Sending one generic CV everywhere
A generic CV is optimised for no one. It will mention skills and experiences in whatever order they were first written, regardless of whether that order is relevant to the role. A recruiter reading a generic CV can tell immediately — the summary does not name the kind of role they are filling, the top bullet points are about a different kind of work, and the skills listed do not reflect the language of their job description.
Tailoring does not mean rewriting your entire CV for every job. It means spending 20 minutes on three specific changes: updating the headline and summary to reflect the role's title and specialism, reordering the bullet points under your most recent roles so the most relevant ones appear first, and checking that the skills section contains the specific keywords from the job description you are responding to.
Most applicants skip this step because it takes time. That is exactly why doing it gives you an advantage. A recruiter reading a tailored CV feels like you wrote it for them — because you partly did.
Mistake 3: Typos and inconsistent formatting
A typo in a CV signals one of two things: that you did not bother to check, or that you checked and missed it. Neither is reassuring when a recruiter is trying to decide whether to spend an hour with you. In some industries — law, finance, communications, medicine — a typo is close to disqualifying on its own.
Formatting inconsistencies are slightly subtler but equally damaging. Using different date formats in different places (January 2022 in one role, 01/23 in another), inconsistent capitalisation of job titles, some bullets ending with a full stop and others not — these details make a CV look assembled carelessly rather than composed deliberately.
The fix: read the document aloud before you send it. Your ear catches errors your eye misses because reading silently lets your brain autocorrect. Then ask someone else to read it. Finally, check specifically for date format consistency, consistent capitalisation, and whether every bullet follows the same grammatical structure.
Mistake 4: Burying the best experience on page two
Recruiters typically spend 6–10 seconds on first contact with a CV before deciding whether to read properly or move on. If your strongest, most relevant experience is at the bottom of page two, it will never be seen. The most important real estate on your CV is the first half of page one.
This mistake often happens when people build their CV in chronological rather than strategic order — they start with education, add a skills section, then list jobs with the most recent first but the most relevant bullets last. By the time the recruiter reaches your best work, they have already made a decision.
Fix: once you have drafted the document, step back and ask: what is the single thing I most want a recruiter to know about me for this specific role? Then check that it appears clearly on the first page, near the top, in the summary or the first bullet of the first role. Move things if they are not. The CV is a marketing document — lead with the strongest material.
Mistake 5: Vague, unmeasurable claims
Phrases like 'improved performance significantly', 'delivered excellent results', 'contributed to business growth', and 'excellent communication skills' appear on hundreds of thousands of CVs and mean nothing to a recruiter because they cannot be verified, compared, or remembered. They are noise.
Every vague claim can be made concrete. 'Excellent communication skills' → 'Presented quarterly results to a board of 12 and wrote the monthly investor newsletter distributed to 340 shareholders.' Now there is something specific that a recruiter can evaluate. 'Contributed to business growth' → 'Part of the founding team that grew annual recurring revenue from £0 to £1.2m in 18 months.' That is a claim that means something.
If you genuinely cannot quantify or specify a claim, ask yourself whether the claim deserves a bullet point at all. If the honest answer is 'I did this task, nothing particularly notable happened', cut the bullet and use the space for something that does have a concrete story.
Mistake 6: CV is too long
Longer does not mean more impressive. A five-page CV from someone with eight years of experience reads as poor editorial judgement — an inability to distinguish relevant from irrelevant, important from peripheral. Recruiters do not read longer CVs more carefully; they read them more quickly because they assume most of it is padding.
The rule of thumb: one page for under five years of experience, two pages for five to fifteen years, and two pages still for most professionals beyond that unless you are in a field where comprehensive records are genuinely expected. Academic CVs are the exception, as noted elsewhere — they grow indefinitely.
To trim a CV that is too long: cut all experience older than 10–12 years to a single brief line per role unless it is directly relevant. Remove bullet points that describe duties rather than achievements. Remove skills that are either obvious (basic computer literacy) or irrelevant to the target role. Cut any section that exists to fill space rather than to demonstrate something.
Mistake 7: An unprofessional email address
Your email address is the first thing a recruiter sees under your name. 'cooldude1998@hotmail.com' or 'partygirl_forever@yahoo.com' undermine everything else on the document before a word of it is read. This seems like a small thing until you consider that a recruiter's first micro-impression of you as a professional is formed in the first two seconds of looking at the header.
The fix is straightforward: create a new email address using your name, ideally in a format like firstname.lastname@gmail.com. If your name is common and that address is taken, add a middle initial or use a professional domain if you have one. Update it on your CV, LinkedIn, and any job board profiles.
While you are reviewing the header, also check that your phone number is correct, that the LinkedIn URL actually works (custom URLs are available for free and look cleaner than the default string of numbers), and that any portfolio link goes to a live, current site rather than a project you abandoned three years ago.
Mistake 8: Dense walls of text
A CV written in paragraphs rather than structured bullets is much harder to scan. Recruiters do not read CVs like essays — they scan them for signals. Long paragraphs force the reader to slow down and hunt for information that should be immediately visible. The result is that they give up before they find it.
Each role should be broken into short, discrete bullets. Each bullet should start with a verb and ideally be no longer than two lines. Group related achievements together under a role rather than mixing them into a single narrative block. Use section headings that are visually distinct from the body text so the reader can navigate without reading every word.
White space is not wasted space. A CV with sensible margins, clear line spacing, and short bullets looks professional and confident. A CV crammed to the edges of the page with minimal margins and tightly packed text looks desperate and is harder to read on screen.
Mistake 9: Missing keywords from the job description
If a recruiter searches their ATS for applicants with 'financial modelling' experience and your CV describes 'building forecast models' without ever using the phrase 'financial modelling', your application may not appear in the results. Similarly, if a job description mentions 'Agile methodology' six times and your CV mentions it zero times, automated scoring systems will rank you lower than candidates who used the exact phrase.
This does not mean keyword stuffing — it means reading the job description carefully, identifying the specific phrases used for the skills and experiences you genuinely have, and then making sure those exact phrases appear in your CV in context. Mirror the vocabulary of the posting, not because it games the system, but because it is the vocabulary the recruiter is thinking in.
A quick method: paste the job description and your CV side by side. Every skill or requirement in the 'essential' section of the posting should map to something in your CV. If you have the experience but used different language, update the language. If you do not have the experience, do not fabricate it — but do consider whether a stretch interpretation of something you do have is honest and defensible in an interview.
Mistake 10: No clear headline or summary
A CV that begins with your name and immediately launches into a list of jobs gives a recruiter no context. They have to read through your entire history to understand what you are actually applying for. By that point, they have already decided how to feel about you — and the feeling is that you could not be bothered to help them understand your application.
A headline (one line under your name) and a summary (three to four lines after that) do the orientation work instantly. The headline names the role. The summary explains your level, your strongest area, and what you are looking for. Together they give a recruiter enough to read the rest of the document with the right frame of reference.
The most common reason people omit the summary is that they find it hard to write — it requires deciding what you most want to say about yourself, which forces clarity about your own positioning. That difficulty is exactly why doing it is valuable. The summary is not an afterthought; it is the thesis statement of your application.
