What Is an ATS and How Does It Read Your Resume?

Over 90% of large companies use an Applicant Tracking System (ATS) to manage applications. Understanding how it works is the difference between an interview and the reject pile.

What an ATS actually does

An ATS parses your resume into structured data (name, contact, work history, skills), then ranks it against the job's requirements using keyword matching. Recruiters often filter by these scores before reading a single resume.

Why resumes get rejected

  • Missing keywords from the job description
  • Fancy layouts, tables, or graphics the parser can't read
  • Non-standard section headings
  • Images or text inside headers/footers

How to beat the ATS

Use a clean, single-column layout, standard headings (Experience, Education, Skills), and the exact keywords from the JD. Test it with our free ATS checker before applying.
