11 Common CV Mistakes That Cost You Interviews

Most CVs are not rejected because the candidate was unqualified. They are rejected because the document failed to make the case, and the person reading it moved on to the next one without ever knowing what they missed.

The frustrating part is that the errors repeat. After you have read a few hundred CVs, the same eleven problems account for most of the pile. None of them are hard to fix. What follows is each one, why it costs you, and a rewritten line so you can see the difference rather than take my word for it.

Mistakes in what you wrote

1. Listing duties instead of achievements

This is the most common and most expensive mistake on the list. A duty describes the job. An achievement describes you doing the job well. Two people with identical responsibilities can be wildly different hires, and only one of them proves it.

Before: Responsible for managing the company's social media accounts. After: Grew Instagram from 2,000 to 15,000 followers in eight months, which lifted inbound enquiries by 40%.

The test is simple. Read the line and ask whether your least effective colleague could have written the same sentence about the same job. If yes, it is a duty.

Which verb you open with changes how the whole line reads, and a list of the ones that carry weight is in CV action verbs.

2. No numbers anywhere

Numbers are what separate a claim from a fact. A CV without a single figure reads as a series of assertions the reader has no reason to believe.

You do not need numbers on every line, and you should never invent them. But most work has a measurable shape somewhere: how many, how much, how often, how fast, how many fewer. If the outcome genuinely cannot be measured, measure the scope instead. Supported 40 stores across three regions is concrete even without a result attached.

If you have read this and concluded that your work simply has no numbers in it, that exact case is answered in how to put numbers on your CV when you think you have none.

3. Buzzwords doing the work of evidence

Hard working. Team player. Detail oriented. Results driven. Passionate. Every candidate claims these, no candidate proves them, and the reader has learned to skip them entirely.

Before: A detail-oriented professional with excellent communication skills. After: Rewrote the onboarding documentation that support used daily, cutting repeat tickets on setup questions by a third.

The second version never claims to be detail oriented. It demonstrates it, and lets the reader draw the conclusion, which is far more persuasive than being told.

Some of these words do belong on a CV, just not in a list of adjectives; which ones earn a place and where they go is covered in what skills to put on a CV.

4. A weak or missing summary

The top third of the first page is the most valuable space you own, and a surprising number of CVs waste it on a generic objective or nothing at all.

Two or three lines. Who you are professionally, how long you have been doing it, what you specialise in, and what you bring. No adjectives that cannot be proven further down.

Before: Motivated professional seeking a challenging role in a dynamic organisation where I can grow. After: Operations analyst with six years in retail supply chain. I build reporting that non technical teams use to make decisions, most recently cutting stock write offs by 18%.

Notice the first version talks about what the candidate wants. The second talks about what the employer gets.

Summaries written out in full for several career stages, career changers and returners included, are in how to write a CV professional summary.

Mistakes in how you built it

5. One CV sent everywhere

Sending an identical document to every advert is the single biggest cause of silence, and it is entirely self inflicted. Employers are not looking for a good CV, they are looking for a match to a specific description.

You do not need to rewrite the whole thing each time. Change the summary, reorder your bullets so the most relevant sit at the top of each role, and make sure the exact terms from the advert appear in your experience where they are true. Fifteen minutes per application.

What those fifteen minutes should actually be spent on, advert by advert, is set out in how to tailor your CV to a job description.

6. Design that stops software from reading it

Multi column layouts, text inside images, skills shown as star ratings, contact details in the page header. These break the parser that reads your CV before any human does, and the failure is silent: your file arrives looking empty rather than looking broken.

This is a big enough topic to have its own guide, and if you have ever wondered why a strong application vanished without a word, start there: how to write an ATS-friendly CV.

7. Length that signals poor judgement

One to two pages. Two is normal once you have a few years behind you, and there is nothing wrong with it. What does damage you is the four page document where a 2009 internship gets the same space as last year's promotion.

Cut anything older than ten to fifteen years unless it is directly relevant, and compress early roles to a single line. The reader is not counting pages, they are noticing whether you can tell what matters.

The right length for your stage, and an ordered list of what to cut first, is in how long should a CV be.

8. Typos and inconsistent formatting

Misspellings suggest carelessness in a document you had unlimited time to check. Inconsistency does the same thing more quietly: dates written three different ways, some bullets ending in full stops and others not, two fonts, mixed tenses.

Read it out loud. Then read it backwards, line by line, which breaks the pattern your brain uses to skip over errors. Then give it to someone who has not seen it.

The full ordered sequence, including the checks worth doing once rather than every time, is in the 15 minute check before you send your CV.

Mistakes that raise doubts

9. Gaps left unexplained

A blank stretch in a timeline invites the reader to guess, and people guess badly. One factual sentence removes the question entirely.

Before: (nothing between 2022 and 2023) After: 2022 to 2023: Career break to care for a family member, with the final six months spent completing a data analysis certificate.

No apology, no elaborate justification. State it and move on.

The wording for each common reason, and the threshold at which a gap is worth mentioning at all, is set out in how to explain employment gaps on your CV.

10. Timelines that are hard to follow

Month and year on every role, consistently formatted, in reverse chronological order. That is the whole rule. If you have held overlapping roles or done contract work, group them clearly rather than interleaving them, and label contract positions as such so a reader does not mistake short stints for job hopping.

A history that is genuinely hard to present in order is usually a format question rather than a wording one, and the three options are compared in CV formats compared.

11. Contact details that are missing, stale, or unprofessional

It happens more than you would believe: a CV with no phone number, an email address from a university account that expired two years ago, or an address like `partyanimal_99@`. Put your name, city, phone, professional email, and LinkedIn at the top of the page in plain text, and check that every one of them still works.

Which of these fields are expected, optional or better left out changes by country, and the country by country breakdown is in personal details on a CV.

The mistake behind all the others

Never looking at your CV the way an employer's system does. You cannot see your own blind spots by rereading, because you already know what you meant to say. The parser does not, and neither does a stranger reading it for six seconds.

Frequently asked questions

How many bullet points should each role have?

Three to five for recent and relevant positions, one or two for older ones. If a role has eight bullets, some of them are duties in disguise.

Should I include a photo?

It depends entirely on the country. Common in much of continental Europe and in Turkey, discouraged in the UK, Ireland, the US, and Canada. Follow the local norm rather than a universal rule.

Do I need to include references?

No. References available on request takes up a line and says nothing, because everyone assumes references are available on request. Remove it and use the space for something that argues your case.

Is it a mistake to use a template?

Not at all, provided the template is single column, text based, and free of graphical skill meters. The problem is never templates, it is decorative ones.

How far back should my work history go?

Ten to fifteen years for most people. Beyond that, compress to a single line with job title, employer, and dates, or drop it entirely if it does not support the job you are applying for now.

Should I explain why I left each job?

No. A CV records what you did, not why you moved. Save the explanation for the interview, where you can give it context and read the room.

Find the ones you cannot see

Every mistake on this list is easy to fix once you know it is there. The difficulty is spotting them in your own document.

CvLaunch reads your CV the way an employer's system does, shows you exactly what was extracted from each section, and flags the formatting and wording problems above against the specific advert you are answering. It takes seconds, it is free, and it needs no sign up.
