Applicant tracking system

An applicant tracking system (ATS) is a software application that enables the electronic handling of the entire recruitment and hiring processes.

An ATS is very similar to customer relationship management (CRM) systems, but are designed for recruitment tracking purposes. An Applicant tracking system has 5 main use cases: Filter resumes, Ranking candidates, Tracking applicants, Improving collaboration and ensuring compliance.

The practice of application filtering has caused many candidates to adopt resume optimization techniques similar to those used in search engine optimization when creating and formatting their résumé.

Principle
A dedicated ATS is not uncommon for recruitment-specific needs. On the enterprise level it may be offered as a module or functional addition to a human resources suite or human resource information system (HRIS). Some ATS's may be available to small and medium enterprises through open-source or software as a service offerings (SaaS).

The principal function of an ATS is to provide a central location and database for a company's recruitment efforts. ATS's are built to better assist the management of resumes and applicant information. Data is either collected from internal applications via the ATS front-end, typically located on the company website or extracted from applicants on job boards. Most job and resume boards (Reed Online, LinkedIn.com, Monster.com, Hotjobs, CareerBuilder, Indeed.com, etc.) have partnerships with ATS software providers to provide parsing support and easy data migration from one system to another. Newer applicant tracking systems (often the epithet is next-generation) are platforms as a service, where the main piece of software has integration points that allow providers of other recruiting technology to plug in seamlessly. The ability of these next-generation ATS solutions allows jobs to be posted where the candidate is and not just on job boards. This ability is being referred to as omnichannel talent acquisition.

Recent changes include the use of artificial intelligence (AI) tools and natural language processing to facilitate guided semantic search capabilities offered through cloud-based platforms that allow companies to score and sort resumes with better alignment to the job requirements and descriptions. With the advent of ATS, resume optimization techniques and online tools are often used by applicants to increase their chances of landing an interview call.
