An Applicant Tracking System (ATS) is a software application used by employers and HR professionals to streamline and automate the recruitment and hiring process. It serves as a centralized database for managing job applications, tracking candidates, and facilitating communication between hiring managers and recruiters. The ATS allows employers to post job openings, receive and review applications, screen resumes, schedule interviews, and store candidate information in a structured and organized manner. It helps streamline the hiring process, improve efficiency, and ensure compliance with hiring regulations.

Example: 
ABC Company uses an Applicant Tracking System to manage their recruitment process. When they have a job opening, they post it on their career website and various job boards. Candidates interested in the position submit their applications online, which are automatically stored in the ATS database. The HR team can then review and screen the applications, filter resumes based on specific criteria, and identify qualified candidates. The ATS also enables them to schedule interviews, track the status of each candidate, and collaborate with hiring managers throughout the selection process. Overall, the ATS helps ABC Company efficiently manage their recruitment workflow and make data-driven hiring decisions.
