If you have been told to write "a CV for the ATS" rather than a resume, there is nothing separate to write. In most of the world the two words describe the same document, and the software reads it the same way either way.
Two words, one document
Ask for a CV in London, Dublin, Berlin, Dubai, Lagos or Mumbai and you will usually be handed the same two pages an employer in Chicago would call a resume. The word changed; the document did not.
North America is the real exception. There a CV normally means an academic document: a full record of degrees, publications, conference papers, grants and teaching, used for university posts and research roles. Even there the words get used loosely in some industries, so read the posting rather than assuming.
| Where you are applying | Usual word |
|---|---|
| UK and Ireland | CV for every job |
| Most of Europe | CV, though the local word often differs |
| Middle East, much of Africa | CV |
| India, South Africa, Australia, New Zealand | Both; CV more often in public sector and academia |
| United States and Canada | Resume; a CV is an academic record |
If the posting names one, use that one. It costs nothing and it shows you know the market.
What the software actually sees
An applicant tracking system has no field marked "is this a CV or a resume". It extracts the text from your file, works out which part is experience and which is education, and stores what it found so recruiters can search it later. That happens the same way whichever word sits at the top.
The heading is cosmetic. The structure underneath is not, and plain section headings help the software place your information correctly:
- Experience rather than "Where I have made a difference".
- Education rather than "Academic journey".
- Skills and Certifications as their own headings.
What recruiters search for is also broader than most people expect: not only skills and job titles, but certifications, degrees, location, languages and years of experience. Use the posting's own wording for the things you genuinely have, and never add a skill you do not have because you think the software wants it.
Where the difference is real
The naming is cosmetic. Three things behind it are not, and all three depend on where you are applying rather than on the software.
Length. Two pages is the working expectation across most of Europe and the UK. In the United States and Canada, one page is usual early in a career, with a second page once there is relevant experience to fill it. There is more on this in how long a CV should be.
Personal details. Conventions vary sharply, even within Europe. In the US, UK, Canada and Ireland, date of birth, marital status and photographs are left off, because employers avoid information that could support a discrimination claim. Elsewhere some of those details are accepted or expected. Check the country and the employer, and include a detail only when it is requested or genuinely relevant. Our guide on photographs on a CV covers the most common of them.
Note that your right to work is a separate question from your nationality. "Eligible to work in the EU" answers what an employer needs to know without disclosing more.
Tone. CVs in the UK and Europe often open with a short personal profile. US resumes more often lead straight into achievements with numbers attached.
A human notices those mistakes immediately. The software mostly will not, though formatting mistakes such as columns, text boxes or contact details stranded in a header will trip up both.
The academic CV
For a research or faculty post the academic CV is genuinely a different document, listing publications, grants, teaching and conference work, and running well beyond two pages. "No limit" is not quite true, though: universities and funding bodies often set a maximum, so check the instructions before you start writing.
Most academic hiring still ends with a human committee, but many institutions now run applications through a system first, so the same basics apply: real text, clear headings, and nothing critical hidden in an image.
What to do today
Use the word your target country uses, then spend your effort where it counts. Match the posting's wording for skills you actually have, keep the layout plain enough to parse, and check the result before you apply. The ATS-friendly checklist covers the formatting, whichever word you put at the top.
