Frequently asked
What is an ATS (applicant tracking system)?
An applicant tracking system, or ATS, is the software employers use to process job applications. Platforms like Workday, Greenhouse, and Taleo are used at most large and mid-sized companies. ATS parsers scan your resume for keywords, formatting quality, and required sections, and a low match score often means your resume gets filtered out before a human reads it.
What is an ATS checker?
An ATS checker is a tool that analyzes your resume the way applicant tracking systems do and scores how well it will parse and rank. A good ATS checker tells you which sections, keywords, or formatting choices are hurting you, so you can fix them before submitting instead of after getting ghosted.
How accurate is Zelume's ATS score?
Zelume's ATS score is calibrated against the scoring rubrics real applicant tracking systems use: formatting (25 points), content quality (35 points), keyword match (25 points), and completeness (15 points). We test the checker against the major platforms (Workday, Greenhouse, Lever, iCIMS, and Taleo), so the score you see reflects what recruiters' software will output.
Why is my resume getting rejected by ATS systems?
Resumes get rejected by ATS systems for a few common reasons: images of text or complex tables that don't parse, non-standard fonts the system can't read, missing keywords from the job description, contact info hidden in headers or footers that get stripped during parsing, and PDF layers that obscure the underlying text. Zelume's ATS checker flags all of these.
Do I need to install anything to use the ATS checker?
No, Zelume's ATS checker runs entirely in your browser. Paste your resume text or upload a PDF, optionally paste a job description to check keyword match, and you'll see your score instantly. Nothing is saved unless you sign up for a free Zelume account.
Which ATS platforms does Zelume check against?
Zelume's ATS checker is calibrated against Workday, Greenhouse, Lever, iCIMS, Taleo, BambooHR, SmartRecruiters, Jobvite, and Ashby. That covers the platforms the vast majority of US employers run their hiring through. If your resume scores well against Zelume's rubric, it will parse cleanly across all of them.
Is Zelume's ATS checker free?
Yes, Zelume's ATS checker is free with no account required. Run as many checks as you want against your own resume. Signing up (also free) lets you save your resume, track score improvements over time, and run ATS checks against specific job descriptions.
