Applicant Tracking System

Hiring the right candidate for a job opening is a crucial process in every organization. Companies have various methods for attracting, recruiting, and hiring top talent. One of the most crucial tools for recruiting has been the ATS.


What is an Applicant Tracking System (ATS)?

An Applicant Tracking System (ATS) is a software application designed to automate and streamline the recruitment process. The ATS acts as a central repository for all job applications and provides a single platform for hiring managers to review, track, and manage candidate information. It allows recruiters to post job openings, screen resumes, and communicate with candidates.

The Importance of an ATS

With the increasing number of job applications received by companies, an ATS can significantly improve the efficiency of the recruitment process. An ATS can save recruiters time and effort by automating the tedious and time-consuming tasks involved in hiring.

One of the key benefits of an ATS is that it helps companies to filter out unqualified candidates. The system can scan resumes for specific keywords, qualifications, and experience. This ensures that only the most qualified candidates move forward in the recruitment process, saving recruiters time and effort.

Another advantage of an ATS is that it helps to maintain compliance with federal and state hiring laws. The ATS can track and store all candidate information, including resumes, applications, and interview notes. This ensures that companies have a record of all hiring decisions and can provide evidence of their compliance with hiring laws.

ATS Evolution over the Past 20 Years

The first ATS systems were developed in the late 1990s and early 2000s. These early systems were basic, with limited functionality, and were primarily used by large corporations. They were expensive and required significant IT resources to implement and maintain.

Over the past 20 years, ATS systems have evolved significantly, becoming more user-friendly, affordable, and widely used. The evolution of ATS systems can be broken down into four distinct phases.

Phase 1: Early ATS Systems (1990s - Early 2000s)

Early ATS systems were primarily used by large corporations with significant hiring needs. These systems were expensive, difficult to use, and required significant IT resources to implement and maintain. They were also limited in their functionality, with the main purpose being to store and track candidate information.

Phase 2: ATS Integration with Job Boards (Mid-2000s - Late 2000s)

The second phase of ATS evolution saw the integration of ATS systems with job boards. This integration allowed recruiters to post job openings directly to job boards and receive candidate applications directly in the ATS. This significantly improved the efficiency of the recruitment process, reducing the time and effort required to manage job postings and candidate applications.

Phase 3: ATS Improvements (Late 2000s - Early 2010s)

The third phase of ATS evolution saw significant improvements in ATS systems. These improvements included better user interfaces, improved search functionality, and the ability to track candidate communication. ATS systems became more user-friendly, making it easier for recruiters to manage the recruitment process.

Phase 4: ATS Advancements (2010s - Present)

The fourth and current phase of ATS evolution has seen significant advancements in ATS technology. These advancements include AI-powered candidate screening, automated interview scheduling, and the ability to integrate with other HR systems. These advancements have made the recruitment process even more efficient, reducing the time and effort required by recruiters.


An Applicant Tracking System is a critical tool for every HR professional in today's hiring process. It has significantly improved the efficiency of the recruitment process by automating tedious and time-consuming tasks.
