ATS stands for applicant tracking system. It is the software an employer uses to post a job, collect the applications that come in, store each candidate's details, and move people through the hiring stages. When someone says your resume "needs to pass the ATS," they mean two things: the system has to read your file correctly, and a recruiter searching inside it has to be able to find you. The system itself rarely rejects anyone on its own, and knowing that changes how you should write. Most of what ranks for this question explains the acronym and then warns you that a robot throws out most resumes before a human sees them. That framing sells resume scanners well, but it does not describe how the software is used day to day. This guide separates the two halves: what the ATS does automatically, and what a person does with it.
