What is an applicant tracking system?
An applicant tracking system is the software an employer uses to receive, store and manage job applications. It parses your CV into structured fields and lets recruiters search and filter candidates.
The persistent myth is that an ATS automatically rejects applications by score. Mainstream systems do not generally do that. What they do is parse your document into fields — employers, dates, titles, skills — and make that searchable, so a recruiter filtering for a specific skill sees only candidates whose parsed record contains it.
That still has a real consequence: if parsing goes wrong, you are invisible to the search rather than rejected by it. Text inside images, multi-column layouts, tables and headers or footers are the usual culprits, because they can be read in an unexpected order or skipped altogether.
The practical guidance follows from how parsing works, not from any scoring theory. Use a single-column layout, standard section headings, real text rather than graphics, and the same words the posting uses — if it says "Kubernetes" and your CV says "K8s", a keyword search for the former will not find you.
