Do Applicant Tracking Systems Reject CVs? The ATS Myth, Checked Against Evidence

Applicant tracking systems (ATS) rarely reject a CV automatically because of its formatting or keyword count. In a 2025 survey of 25 US recruiters, 92% said their system does not auto-reject on formatting, design, missing keywords or a low match score. The ATS is mainly a database that recruiters search and sort. The real automatic filters are knockout questions on hard requirements, such as work authorisation, a required licence, minimum qualifications and location, plus a few strict rules like the two-page limit on US federal resumes. For veterans, the bigger risk is a recruiter searching for civilian terms that your military CV never uses.

How common are applicant tracking systems?

Very common. Jobscan's 2026 ATS usage report, its sixth edition, detected an ATS at 97.4% of Fortune 500 companies, 487 of 500. The market is concentrated:

The "75% auto-rejected" myth

The claim that three-quarters of CVs are rejected by software before a human sees them circulates widely. The Enhancv survey, reported in November 2025, asked 25 US recruiters across technology, healthcare, finance, publishing and retail, using more than ten ATS platforms between them, where it comes from and whether it is true.

A recruiter quoted in the report put it directly: "ATS systems don't automatically disposition people - we have to go in and do it ourselves." Twenty-five recruiters is a small sample, so treat this as strong evidence against the extreme version of the myth. It does not prove that no software filtering happens.

Where filtering really happens

1. Knockout questions

The recruiters who did use auto-rejection applied it to work authorisation, required licences, minimum qualifications and location. Answer these questions accurately. A wrong click on "Do you hold a full UK driving licence?" or "Are you authorised to work in the US?" can end an application regardless of the CV.

2. Narrow search criteria

The Harvard Business School and Accenture report Hidden Workers: Untapped Talent (Fuller, Raman, Sage-Gavin and Hines) names veterans among the groups that hiring processes systematically exclude. HR Dive's summary of the 2021 report gives the key numbers: 88% of employers surveyed said qualified high-skilled candidates were vetted out because they did not exactly match the criteria, rising to 94% for middle-skilled candidates. The report describes "negative" filters, such as screening out applicants with a gap in work history or without a particular degree. That is the real mechanism to plan around: a recruiter or a configured rule searches for specific civilian terms, and a CV written in military language does not come up.

3. Strict format rules on US federal jobs

USAJOBS is the clearest case of an automatic rule. Since 27 September 2025, resumes for most federal jobs are limited to two pages. If your only resume is longer, you are found ineligible, with the notice "Your application is not being considered due to not meeting the resume page number requirement in the job announcement." OPM also lists what to include: contact details, and for each relevant job the title, employer and start and end dates in month and year format.

4. Structured sifts in the UK public sector

UK Civil Service applications are usually sifted by people against published criteria. Applications are assessed against Success Profiles behaviours and experience, often through written statements. The words that matter are the behaviours named in the advert.

Myth and reality

Making a military CV searchable

Recruiters search for the job title and skills in their advert. Your CV needs those terms where they honestly apply. The table shows typical military wording and the civilian search terms a recruiter is likely to use. Use the O*NET Military Crosswalk to find more terms for your own role.

Two example bullets, written for this guide, show the change:

• Before: "SQMS for a sub-unit; responsible for G4 support and equipment care." After: "Logistics and inventory manager for a 120-person team; ran procurement, stock control and a planned maintenance programme for vehicles and equipment."
• Before: "Unit Safety Rep, conducted RA for all ranges and exercises." After: "Health and safety lead; wrote and reviewed risk assessments for live training activities involving up to 200 people."

Formatting that parses cleanly

The Career Transition Partnership's CV guidance anticipates electronic submission: keep the CV "internet friendly", keep job headings simple (HM Forces, job title, years), avoid graphics and cluttered layouts, use a common business font, and keep to two pages. The National Careers Service adds clear headings, bullet points, a consistent style and a font such as Arial or Calibri at size 11 or larger. Recruiters in the Enhancv survey asked for the same things: short, achievement-focused bullets (72%) and no more than two pages (64%).

A practical checklist before you upload:

• Save as the file type the advert asks for. If none is stated, a Word document or a text-based PDF is the safer choice.
• Use standard headings: Profile, Experience, Education, Qualifications, Skills.
• Keep contact details in the main body of the page, outside headers, footers and text boxes.
• Spell out each acronym once, or replace it.
• Read the advert twice and check that its core job title and three to five key skills appear in your CV where they are true.
