What is an ATS?
An Applicant Tracking System (ATS) is software designed to centralize and automate the recruitment process. These systems simplify complex hiring processes by managing job applicants, tracking candidate status, and screening resumes for qualified candidates. With the integration of artificial intelligence in modern ATS software, businesses can significantly reduce the time to hire, improve candidate engagement, and create efficient hiring workflows that align with their hiring goals.
