ATS Resume Checklist: What Actually Gets You Filtered Out

Applicant tracking systems don't "reject" resumes with judgment — they fail to parse them correctly, and a recruiter never sees the missing sections. Multi-column layouts, text inside images or tables, and headers/footers holding contact info are the most common parsing failures.

Keyword matching matters, but not the way most advice implies: it is not about stuffing a skills list, it is about using the same terms the job description uses for the same concept — "React" not "front-end framework," "PostgreSQL" not "relational database" — so the ATS's literal string match actually fires.

Section headers should be conventional ("Experience," "Education," "Skills") rather than creative, since ATS parsers pattern-match on standard headings. Dates need a consistent, unambiguous format so tenure calculations don't break.

A resume can pass ATS parsing and still read poorly to the human afterward — the two problems are different and both need checking. InterviewOS's resume analysis checks both: ATS-safe structure and keyword coverage against a specific job description.
