Screening is elimination, not selection. Someone has 200 applications and four interview slots, so they are not looking for reasons to say yes — they are looking for the fastest defensible reason to say no.
Weak experience gets you a polite no at the end. A detail that looks careless or evasive gets you a no in the first fifteen seconds, whatever is further down the page. All nine of the following are fixable in an afternoon.
1. Gaps left unexplained
A gap is not the problem. An unexplained gap is, because the reader fills it in themselves and their guess is worse than the truth.
Caring responsibilities, illness, redundancy, travel, study, parental leave, a business that did not work — all read as ordinary in one line and suspicious as a hole. Put it in the employment history at the right point: "2023–2024 — Career break, full-time caring responsibility. Returned to work September 2024."
You owe no detail beyond that and should not give any.
2. Dates that do not reconcile
Screeners check dates, and quickly. Common failures: a role that ends after the next one starts, a promotion listed as a separate job with overlapping dates, and months on some entries with years on others.
Use one format throughout — "Mar 2023 – Present" — and months everywhere or years everywhere, not a mixture. Mixing formats is the most common way an innocent history looks like it is hiding something.
If you were promoted internally, show the employer once with the roles nested underneath. Listing them as two employers with contiguous dates reads as job-hopping that never happened.
3. A summary that could belong to anyone
"Results-driven professional with a proven track record of delivering excellence in fast-paced environments." This appears near-verbatim on a large share of applications for any role. It costs three lines at the top of the page and communicates nothing.
Either write a summary only you could have written — specialism, years, scale, what you are actually known for — or delete it and let the experience start at the top. Deletion is the better default.
4. Duties instead of outcomes
A job description says what the role involved. A CV should say what happened because you were the one doing it.
"Responsible for managing supplier relationships" is a duty. "Renegotiated terms with 12 suppliers during a cost review, holding unit prices flat through a year of input inflation" is an outcome. The first could describe anyone who held the title.
This is the biggest quality difference between CVs that get calls and CVs that do not, and the most work to fix, which is why most people fix the other eight instead.
5. Tools listed on the strength of one afternoon
A skills section with eighteen tools invites a question about any one of them, and experienced interviewers ask about the ones in the middle. Being unable to discuss something you listed damages everything else you claimed.
List what you could work in tomorrow without help. Mark beginner-level tools as such or leave them off. Nobody was ever shortlisted for listing more software.
6. Photos and dates of birth where they are a liability
This is market-specific and getting it wrong is costly.
In the UK, Ireland, the US, Canada and Australia, do not include a photograph, date of birth, marital status or nationality beyond your right to work. Many employers there must demonstrate non-discriminatory screening, and some discard a CV containing protected characteristics rather than create a problem.
In much of continental Europe a photograph and date of birth remain conventional, and omitting them can read as incomplete. In parts of Asia, additional personal detail is standard. Follow the employer's local convention, not your own.
Fix the mechanical ones first
Dates, file name, email address, layout and the gap line take about an hour between them and remove most of the reasons an application is dismissed before it is read. Rewriting duties into outcomes is the higher-value change but it takes a weekend — do the hour first.
7. An email address that undermines you
A personal address created in your teens, a joint household address shared with a partner, or an address at your current employer's domain. All three register.
The third is worst: using a work email for a job search tells a prospective employer you are comfortable using one employer's resources against their interests, and it is how a lot of people are discovered to be looking. Use a plain personal address based on your name.
8. A badly named file
Your CV lands in a folder alongside 200 others and its filename identifies it. "cv_final_v7.docx" puts the burden of renaming on the recruiter, and "CV.pdf" is indistinguishable from everything else there.
Name it "Firstname Lastname CV.docx". It takes four seconds and it is the only part of the process where you control how your application is filed.
Nothing on this list makes you a better candidate. All of it stops you being dismissed as a worse one than you are.
9. Design that breaks the parser
Heavily designed templates — two columns, sidebars, skill rating bars, icons in place of contact labels, text inside graphics — look considered and parse badly. The outcome is worse than rejection: your experience lands in the wrong field or vanishes, and the version a recruiter searches is missing half of what you wrote.
Single column, conventional headings, contact details in the body text at the top, a standard font at 10 to 12 point. Save a copy as plain text and read it. If that is coherent, the parsed version will be too.
The exception is design and creative roles where a portfolio is expected — and even there, send a plain parsable CV alongside it, not instead of it.
