What is an Applicant Tracking System, and how does it work?

Companies use applicant tracking systems to aid in the recruitment and hiring process. Each system has its own set of capabilities however ATS are largely intended to assist hiring organizations in collecting, organizing, and filtering candidates.

An applicant tracking system (ATS) is used by job seekers who submit their résumé and application using an online form.

Why Do Job Seekers Have a Problem With Applicant Tracking Systems?

Corporate recruiters can have their applicant tracking systems (ATS) take data from an applicant’s résumé to create a digital applicant profile that can be searched, filtered, and ranked. The purpose is to immediately weed out everyone who is underqualified, reduce the applicant pool, and discover the best applicants as quickly as possible.

Because their CV has formatting flaws or lacks the relevant search keywords, some highly competent candidates slide through the cracks and are wrongly excluded from the application pool.

For many hiring professionals with limited time and resources, this is a necessary tradeoff. Job searchers must optimize their resumes for ATS in order to be discovered.
