You've probably read that three in four CVs are rejected by software before a person sees them. It's repeated everywhere, and it sells a lot of CV scanners. It also has no study behind it.
An applicant tracking system, or ATS, is real and nearly every larger employer uses one. But it's mostly a filing cabinet with a search box, not a robot that reads your CV and says no. Knowing what it actually does tells you which fixes matter and which ones are a waste of an evening.
Where the 75% came from
The figure traces back to a 2012 sales pitch from Preptel, a company that sold CV optimisation and closed the following year. Its method was never published. Articles quoted it, later articles quoted those articles, and a sales line became a "statistic".
When recruiters are asked, the picture is different. In a 2025 study by the CV builder Enhancv, 23 of 25 recruiters said their system does not reject CVs for their formatting or content. The two exceptions had set strict match thresholds on purpose. It's a small survey from a company with its own interest, so treat it as a hint, not proof. But it matches how the systems are built.
What an ATS actually does
- Reads your file
A parser pulls the text out of your PDF or DOCX and sorts it into fields: name, contacts, roles, dates, education, skills.
- Stores it
Your application sits in a list for that job, next to everyone else’s, usually newest first or in the order they arrived.
- Asks the knock-out questions
Right to work, location, a required licence, a language level. These are set by the employer, and a “no” can close the application automatically.
- Lets a recruiter search
Recruiters filter by keywords, job titles or places, today and for later roles. That is where the posting’s own words matter.
- Sometimes ranks
Some systems add a match score. Many recruiters switch it off or skim past it, but it exists, and it reads the same parsed text.
In Workday, SAP SuccessFactors, Personio, Greenhouse, Teamtailor or any of the others, the order is the same: the system reads your file, then a person reads what it read.
Five myths, and what is true instead
- “Robots reject most CVs.” People do the rejecting, usually after a few seconds of reading. A large share of CVs is never opened because a role gets hundreds of applications, not because software turned them down.
- “Only a DOCX gets through.” Modern parsers read a PDF with real text as well as a DOCX. Send what the posting asks for; if it says nothing, a PDF keeps your layout.
- “Hide keywords in white text.” The parser reads them and shows them to the recruiter as plain text in your profile. It looks like a trick, because it is.
- “You need an ATS score of 80%.” There is no shared score. Every scanner's number is its own, and none of them is the one your employer uses.
- “Design doesn't matter.” This one is half true. Nobody rejects you for a nice layout, but two columns, text boxes and icons can come out of a parser in the wrong order, and then your phone number or job title is wrong in the system.
An ATS rarely says no. It just reads, and sometimes reads badly.
What really gets a CV lost
Volume and timing. A popular role can draw hundreds of applications in a few days. Applying early, while the list is still short, often matters more than any format change.
A wrong answer on the form. If the posting needs a work permit, a driving licence or a language at C1, the form asks and the answer filters. Read the questions carefully before you click.
A scrambled parse. If your name comes after a date, or your email is split across two lines, the recruiter sees a broken profile. You can see what a parser reads before you apply: the free ATS check shows the text in the order a system takes it out, with eight checks.
A title nobody searches for. Recruiters search by job title. If you were a "Customer Happiness Hero" and the role is "Customer Support Specialist", put the plain title beside yours.
In the EU there is one more safeguard. Under the GDPR you have the right not to be subject to a decision based solely on automated processing when it significantly affects you, and you can ask for a person to review it. If an application closes in seconds with no reason given, you're allowed to ask how it was decided.
- Your name is the first line of the CV, and your email and phone each sit on one line.
- One column, real text, standard headings: Experience, Education, Skills.
- The job title you held, in words a recruiter would search for.
- The posting’s must-haves named in your CV, where they’re true.
- Every question on the form answered as carefully as the CV itself.
