Guides

How an ATS actually reads your résumé

Twelve plain-language guides in reading order, written by the people who built a résumé parser. No recycled advice — the parser behavior shown here is reproducible with the checker.
01

What is an ATS? What it actually does with your résumé

The software behind the "apply" button: what it stores, parses, and searches — and the judgment it doesn't make.

02

What happens to your résumé before a recruiter sees it

The pipeline between your click and human eyes — extraction, field mapping, profile, search — and each step's failure mode.

03

Why résumés get "rejected by the ATS"

Parsing failure, search miss, or human decision — the three real failure modes, and how telling them apart changes what you fix.

04

What actually breaks ATS résumé parsing

Tables, header contact info, multi-column layouts, and icon fonts — why each one fails, shown with real parser output.

05

ATS-friendly résumé format: the checklist with reasons

Ten verifiable properties, each mapped to the parser failure it prevents — plus what doesn't matter as much as people say.

06

PDF or DOCX for your résumé?

DOCX stores structure; PDF stores ink positions. What that difference does to your file — and when a PDF is perfectly fine.

07

ATS keyword optimization, honestly

Exact words beat synonyms, hard skills carry the weight, and stuffing fails mechanically — the per-posting playbook.

08

Seven ATS myths that cost applicants real interviews

Auto-rejection, universal scores, white-text tricks, "certified" templates — persistent myths, corrected mechanically.

09

How to check if your résumé is ATS-friendly

No universal "pass" exists — but extraction, field identification, and coverage are checkable. The five-step self-test.

10

The ATS résumé checklist

The whole routine sorted by frequency: structure once, keywords per application, and a two-minute pass before sending.

11

What free ATS résumé checkers actually do

Where the scores come from, what "free" is paid with, and five questions that judge any checker — this one included.

12

What happens to your résumé when you upload it

What upload-based checkers can do with your file, five privacy-policy checks, and how to verify a no-upload claim yourself.
