What is an ATS Resume? The Complete Guide to Getting Past the Robots

Here's a frustrating reality: you could be the perfect candidate for a job, but if your resume isn't optimized for ATS (Applicant Tracking System), it might get rejected before a human ever sees it. Studies show that up to 75% of resumes are filtered out by these automated systems. That's not a typo – three out of four applicants are eliminated by software, not people.

But don't panic. Once you understand how ATS works, beating it becomes surprisingly straightforward. This guide will walk you through everything you need to know about creating an ATS-friendly resume that actually lands on a recruiter's desk. And our free resume builder creates perfectly optimized resumes automatically.

What Exactly is an ATS?

An Applicant Tracking System is software that companies use to manage job applications. Think of it as a digital gatekeeper that receives, sorts, and ranks resumes before any human gets involved. Almost every medium to large company uses one – we're talking about 99% of Fortune 500 companies and about 75% of all employers.

Popular ATS platforms include Workday, Taleo, Greenhouse, Lever, and iCIMS. If you've ever applied through a company's career portal (instead of emailing a resume directly), you've interacted with an ATS.
