Most rejected CVs are never read. They are parsed, scored and filtered. Here is how applicant tracking systems actually work, and how to write a CV that survives them without sounding like a robot.
Before a recruiter sees your CV, software reads it. An applicant tracking system parses your file into structured fields, matches it against the job requisition and produces a ranked list. Recruiters typically review the top slice of that list. This is not a conspiracy against candidates — it is what happens when one posting attracts several hundred applications — but it does mean a strong career can be invisible because of a two-column layout and a missing noun.
What an ATS actually does
The system performs four operations: it extracts text from your file, maps that text to fields (name, contact, employment history, education, skills), matches keywords and requirements from the job description, and ranks or filters the result. Some systems add knock-out questions — work authorisation, years of experience, a required licence — that filter you out regardless of the rest.
Two consequences follow. First, anything the parser cannot read does not exist. Second, the vocabulary of the job description matters more than the elegance of your prose.
Formatting rules that keep you readable
- Send a .docx or a text-based PDF. Never a scanned or image-based PDF, and never a design tool export that flattens text.
- Single column. Two-column layouts frequently interleave into nonsense during extraction.
- No text in headers, footers, text boxes, tables or images. These are the most common places for a phone number to disappear.
- Standard section headings: Summary, Experience, Education, Skills, Certifications. Creative headings such as “Where I’ve Made Noise” break field mapping.
- Standard fonts and simple bullets. Decorative glyphs can be dropped entirely.
- Dates as Month Year – Month Year, consistently, so tenure calculations work.
- File name: firstname-lastname-role.pdf.
Keywords without keyword stuffing
Paste the job description into a document and highlight every repeated noun: tools, methods, certifications, domains. Those are your target terms. Then place them where they are also true: in the summary, in the relevant role bullets and in the skills list. Spell out an acronym once with its expansion — “Search Engine Optimisation (SEO)” — because different systems index one or the other.
Do not paste a white-text keyword block. Modern systems flag it, and recruiters who spot it reject on integrity grounds. Density is not the goal; being genuinely described in the employer’s vocabulary is.
A section-by-section template
Contact block
Name, city and country, phone with country code, professional email, one profile link. No photograph, date of birth or marital status unless the country you are applying in expects it.
Professional summary
Three lines: your role and years of experience, two or three specialisms taken from the posting, and one quantified achievement. Rewrite this per application; it is the highest-leverage 40 words on the page.
Experience
Reverse chronological. For each role: job title, employer, location, dates, one line of context (team size, scope, budget) and three to five achievement bullets. Every bullet follows action verb + task + measurable result. “Reduced monthly close from nine days to four by automating three reconciliations” beats “responsible for month-end close” in both parsing and human reading.
Education, certifications, skills
Degree, institution, graduation year, and grade only if it helps. List certifications with the issuing body and year. Keep the skills section factual and grouped — tools, languages, methods — and drop self-ratings like “expert”.
Handling gaps, career changes and international CVs
Employment gaps are ordinary. State the period and one neutral line — caregiving, study, health, relocation — and move on. For a career change, lead with a summary that frames the transferable core and add a short “Relevant projects” section above older roles so the parser and the reader hit your evidence early.
Country conventions differ: North American resumes are one to two pages with no photo; several European markets expect a photo and date of birth; academic CVs are unlimited length with publications. Match the market you are applying to rather than exporting one file everywhere. If you are applying across borders, our study abroad section covers the documentation and rights questions that follow.
Test your CV before you send it
- Save it as plain text and read the result. Anything scrambled or missing will be scrambled or missing for the parser.
- Check that every job description requirement is answered somewhere true on the page.
- Count achievement bullets with numbers; aim for at least half.
- Read the first six lines only. If they do not identify you as a credible candidate for this exact role, rewrite them.
- Run a spellcheck in the employer’s language variant, then have one person proofread it.
Consult a reputable public reference for national conventions and rights when you are unsure — for example Europass for European CV formats.
Ten mistakes that keep good CVs invisible
- Two-column or infographic layouts.
- Contact details in the header.
- A generic summary reused across every application.
- Duty lists instead of achievements.
- No numbers anywhere.
- Acronyms without expansions.
- Creative section titles.
- Skills the interview will disprove.
- Inconsistent date formats.
- A five-page history for a three-year career.
Frequently asked questions
Should my CV be one page or two?
One page under five years of experience, two pages beyond that. Academic and public sector formats are the exceptions.
Do cover letters still matter?
They matter where a human reads them — smaller employers, research groups and public sector roles. Keep them to four short paragraphs and make them specific.
Should I tailor every application?
Tailor the summary and the top three bullets of your most recent role. That is roughly fifteen minutes and it is where nearly all the ranking gain sits.
