Do applicant tracking systems reject resumes?

What an applicant tracking system does

An applicant tracking system (ATS) is the software an employer uses to collect applications for a job. It stores each resume, pulls out the text into a candidate profile, and lets recruiters search, sort and move people through hiring. The full walk-through is in what is an ATS.

Its default job is to hold and organise applications. Rejecting people is something an employer has to set up, and most rejections are still made by a person.

What recruiters say

The best evidence we have is small, so read it as that. Enhancv interviewed 25 US recruiters in September and October 2025, across industries and company sizes, using systems such as Workday, iCIMS, Lever and Greenhouse. Of those 25:

• 23 (92%) said their systems do not reject resumes on their own for formatting, content or design.
• 2 (8%) had set up automatic rejection based on match scores or skills.
• All 25 said they use knockout questions (yes or no eligibility checks). Teams can send people who fail them to a recruiter, or set them to reject automatically.
• 13 (52%) said applying early helps, because they review applications in the order they arrive.

Twenty-five interviews do not describe every employer. But they match how the software is built and what vendors document.

What does screen people out automatically

Knockout questions. These are the yes or no questions on the application form: work authorization, a required license, willingness to work in a location or on a shift. An employer can set a wrong answer to reject you straight away. Greenhouse, for example, documents an "auto-reject" rule that uses candidates' answers to the employer's application questions, to filter out people who do not meet essential criteria such as a license or location.

Ranking and matching, where employers turn it on. Some systems can score or order candidates by fit. A low score usually means you sit lower in the list, and in a pile of hundreds a low place can mean nobody gets to you. A minority of employers also reject on those scores.

Where resumes really get lost

A resume is rarely deleted by the software. It gets lost in quieter ways:

1. Volume. Popular roles get hundreds of applications. Recruiters stop reading when they have enough good candidates, so late or buried applications are never opened.
2. The software misreads it. If your experience comes out garbled or in the wrong order, it will not match the searches recruiters run.
3. It does not match the search. Recruiters filter by job titles, skills and locations. If your resume calls a skill something else, it may not come up.

The "75% of resumes are rejected" claim

You will see it everywhere: "75% of resumes are rejected by ATS before a human sees them." We could not find a published study behind it, with a sample, a method or a date. Without one, the number tells you nothing. Enhancv, after interviewing recruiters, reached the same conclusion: the figure is repeated widely, usually with no source. Treat it as a myth until someone publishes the data.

What you can do

• Answer knockout questions carefully and honestly. They are the one place a machine can say no on its own.
• Apply early in a posting's life when you can.
• Use a single-column layout and standard headings like Experience and Education.
• Keep text as text, never inside an image.
• Use the words from the job posting where they are true for you.
• Check how the software reads your file before you send it. Our checker and its full report are free, with no account.
