ATS, an abbreviation for "Applicant Tracking System," is a type of recruiting software that helps the company streamline its hiring process from beginning to end. Many organizations use ATS to analyze and improve their current hiring process. It helps to post job openings on multiple job portals, stores applicant data, and screens the applications for potential matches. A lot of filters, such as experience, qualification, skills required, etc., are used to determine the candidate’s suitability for a position. An advanced ATS has an in-built communication system, which provides communication channels between the recruiter and the potential candidate.
