Applicant Tracking System (ATS)
Definition
An Applicant Tracking System (ATS) is a software application used by human resource departments and recruiters to filter, organize, track, and rank job applications. When candidates submit resumes online, the ATS parses the text layer, matching keyword frequencies and structuring sections to present matching candidates on recruiter dashboards.
Why it matters for job seekers
Over 95% of Fortune 500 companies and growing startups use ATS platforms to filter candidate pools. If a resume features complex layouts, scanned images, or table blocks, the parser fails to read the text cleanly, which results in candidate rejection before a human recruiter reviews the application.
Formatting Best Practices
- Use a clean, single-column template format to ensure left-to-right parsing.
- Adopt standard section names such as "Work Experience", "Education", and "Skills".
- Export resumes as PDFs with selectable, machine-readable text layers.
- Avoid placing contact details or major text inside headers or footers, as some parsers skip these.
Apply this optimization immediately
Scan your resume using the ATS checker or choose an ATS-tested template to ensure your details parse correctly.
