"ATS" gets thrown around like it's some mysterious AI gatekeeper deciding who gets an interview. It isn't. An applicant tracking system is just software that extracts text from your CV and displays or searches it for a recruiter - and like any parser, it can only work with what it can actually read. Careevio's own CV ATS X-Ray uses the same kind of deterministic, rule-based checks described here, which is why it's worth understanding what's actually going on under the hood.
What an ATS actually does
Most systems do three simple things: pull the raw text out of your PDF or Word file, try to identify sections (contact details, experience, education, skills), and store the result so a recruiter can search or filter it later. None of this involves understanding your CV the way a human does - it's closer to copy-pasting text out of a document than to reading it.
Common formatting issues that trip up parsers
Because parsing is mechanical, formatting choices that look fine to a human can scramble the extracted text or hide it completely:
- Multi-column layouts. Simpler parsers read left-to-right across the whole page, not down one column then the next - so a two-column CV can come out with your job titles and dates interleaved in the wrong order.
- Text inside tables or text boxes. Some parsers skip content that isn't in the main text flow entirely.
- Headers and footers. Contact details placed in a page header/footer are sometimes dropped rather than parsed.
- Non-standard section titles. "My Journey" instead of "Experience" can confuse automatic section detection.
- Text as images. Anything rendered as a picture (including some exported-from-design-tool PDFs) usually can't be read as text at all.
A two-minute self-check
Before you send your next application, try this: open your CV PDF, select all the text (Ctrl/Cmd+A), copy it, and paste it into a plain text editor. If your name, job titles, dates or bullet points come out jumbled, missing, or in a strange order, there's a reasonable chance a real ATS would have the same trouble.
What to do next
Single-column layouts, standard section headings, and text that's actually text (not an image) will parse cleanly almost everywhere. If you'd rather not do the copy-paste test by hand, Careevio's CV ATS X-Ray runs this kind of check automatically and shows you exactly what a basic parser would see - free to try, no account required.
