What is an ATS? Complete Guide for Job Seekers

What is an ATS?

An Applicant Tracking System (ATS) is software that companies use to manage their hiring process. It collects, sorts, scans, and ranks resumes submitted for job openings.

How Do ATS Systems Work?

When you submit your resume online, it goes through these steps:

  • Parsing — The ATS extracts text from your resume and identifies sections
  • Keyword Matching — It compares your resume keywords against the job description
  • Scoring — Your resume receives a relevance score
  • Ranking — Candidates are ranked by score for recruiter review
  • Popular ATS Systems

  • Workday — Used by 50%+ of Fortune 500
  • Greenhouse — Popular with tech companies
  • Lever — Common in startups
  • iCIMS — Used across industries
  • Taleo (Oracle) — Enterprise favorite
  • How to Beat ATS

    The key is to make your resume ATS-friendly while still being compelling for human readers. Use our AI Resume Builder to automatically optimize for both.
