Transparent scoring
ATS Resume OS runs 27 checks across 5 categories, totaling 100 points normalized to a 0–100 score. No black box — here is exactly what we measure.
Important:No tool can perfectly replicate every employer's ATS. Our score measures proven compatibility factors used by systems like Workday, Greenhouse, and Taleo. Use it as a guide to improve — not as a pass/fail guarantee.
ATS must extract text from your file. Scanned image PDFs fail this check.
Tables and pipe characters often break ATS parsing.
Two-column designs confuse parsers — single column is safest.
Text in graphics or boxes may not be extracted.
Files under 4MB upload reliably across systems.
Recruiters need a direct way to reach you.
A phone number increases callback rates.
LinkedIn gives recruiters more context on your background.
City and state help with location-based filtering.
Avoid unprofessional handles like partygirl@ or similar.
A brief summary sets context in the first 7 seconds.
Experience is the core section every ATS expects.
Degree and institution help qualify you for roles.
A dedicated skills block improves keyword matching.
Bullets are easier for ATS and humans to scan.
Led, built, increased — strong verbs signal impact.
Numbers (%, $, team size) prove results.
Consistent dates help ATS build your timeline.
Replace "responsible for" with achievement bullets.
Ideal range is roughly 400–900 words (1–2 pages).
Role-relevant terms improve match scores.
At least 4 distinct skills strengthens keyword coverage.
Leadership, communication, and teamwork matter.
Certs add credibility for technical roles.
Arial, Calibri, and similar fonts parse reliably.
Standard headings like Experience and Education help parsing.
PDF and DOCX are the safest formats.
