What is an applicant tracking system?

Short answer

An applicant tracking system (ATS) is the software a company uses to post jobs, take applications and move candidates through hiring. The most common in landed’s index are Greenhouse (64,319 roles), Workday (57,735 roles), Ashby (43,819 roles), SmartRecruiters (29,883 roles), Lever (11,899 roles).

What it does with your application

It stores your form answers and résumé, usually parses the résumé into fields, and puts you in a pipeline a recruiter reviews. Ranking, if any, is configured by each employer.

How systems differ

Greenhouse needs no account to apply; Workday employers can require an account per company; SmartRecruiters requires only name, email and the screening answers.
