Question 1

What is an ATS resume checker?

Accepted Answer

An ATS resume checker scans your resume the same way Applicant Tracking Systems (ATS) used by companies do. It checks if your resume has the right keywords, correct formatting, and proper section headers so it isn't automatically rejected before a human reads it.

Question 2

Why does my resume fail ATS?

Accepted Answer

Common reasons resumes fail ATS: missing role-specific keywords, two-column layouts that ATS can't parse, tables or graphics, generic section headers, no measurable achievements. CareerLens identifies exactly which issue is hurting your score.

Question 3

Is this ATS checker really free?

Accepted Answer

Yes — CareerLens gives you a full ATS score, missing keywords, and top 3 improvements for free, with no login required. Pro users get deeper analysis and AI resume rewrites.

Question 4

How accurate is the ATS score?

Accepted Answer

CareerLens uses the same logic as major ATS platforms (Workday, Greenhouse, Lever) — keyword matching, format parsing, and section detection. Most users see their callback rate improve after fixing the issues flagged.
