An Applicant Tracking System is an online platform used by recruiters and in-house HR teams to screen candidates during the recruitment process. The platform allows candidates to be entered into the system and have their progress from job application to onboarding tracked. It also acts as a CRM (Customer Relationship Management) tool to allow recruiters to keep on top of each candidate’s application journey and to maintain communication at each hiring stage. An ATS can parse or migrate data from candidate resumes submitted via online job boards which are added to the central database. A good ATS can greatly improve the candidate hiring process, decreasing the amount of time it takes to make a hire and increasing the productivity of the recruiter enabling them to fill more jobs. Newer platforms integrate third-party providers to bring a greater degree of flexibility to the core system, from background checks to payroll services.
