Does passing every check guarantee my resume will get through a real ATS?

No — these are common ATS pitfalls, not a simulation of any specific vendor's parser, since real Applicant Tracking Systems vary widely by company and configuration; treat a passing score as reduced risk, not a guarantee.

Why did it flag missing section headers when I clearly have an 'Experience' section?

The check looks for the literal words 'experience,' 'education,' and 'skills' anywhere in the text — a resume using synonyms like 'Employment History' or 'Qualifications' instead of the standard headers will fail that check even though a human reader would understand it fine.

How it works

The checker runs your resume text through six pattern-based rules: regexes for a valid-looking email and phone number, a search for the words "experience," "education," and "skills" as section headers, a word count in the 250-to-900 range, at least two bullet-point lines (dashes, asterisks, bullets, or numbered lists), and a check that uppercase letters make up less than 30% of all letters. All of it runs against the text right in your browser.
