Introduction
Hiring has changed dramatically over the past few years. Companies no longer manage recruitment with stacks of printed resumes, spreadsheets, long email chains, and separate calendars. As the number of applications grows and hiring teams work across different locations, businesses need technology that can keep the entire recruitment process organized.
This is where an Applicant Tracking System (ATS) becomes important.
An Applicant Tracking System is recruitment software that helps organizations collect applications, organize candidate information, manage job postings, screen applicants, schedule interviews, communicate with candidates, and track hiring progress from one central platform.
Modern ATS platforms can do much more than simply store resumes. Depending on the product, they may connect with job boards, career websites, HR systems, assessment platforms, calendars, background-check services, analytics tools, and recruitment marketing systems.
According to Jobscan’s 2025 research, an ATS was detectable at 97.8% of Fortune 500 companies, or 489 out of 500 organizations. Its research also found that the figure was 98.4% in 2024. The remaining companies may use proprietary systems that are not detectable externally.
That level of adoption shows how important recruitment technology has become for large organizations.
But what exactly does an ATS do, how does it work, how does AI affect modern hiring, and what should businesses and job seekers know before using one?
Let’s break it down.
What Is an Applicant Tracking System (ATS)?

An Applicant Tracking System is software designed to organize and manage the recruitment process.
Think of it as a central workspace for hiring.
Instead of keeping one candidate’s resume in an email inbox, interview notes in a spreadsheet, feedback in a messaging application, and application status somewhere else, an ATS brings much of this information together.
A typical system can help recruiters:
- Create and publish job vacancies
- Collect applications
- Store candidate profiles
- Parse resume information
- Search candidate databases
- Filter applicants according to defined criteria
- Schedule interviews
- Communicate with applicants
- Collect interviewer feedback
- Track hiring stages
- Manage offers
- Generate recruitment reports
- Maintain records for compliance and auditing
Workday describes an ATS as a central database that supports recruiters and employers throughout the hiring journey, including job posting, application collection, screening, interview management, and candidate evaluation.
The exact capabilities differ between vendors. A small company may need only job posting, resume management, interview scheduling, and basic reporting, while a global organization may require complex workflows, integrations, analytics, permissions, automation, and multilingual career sites.
ATS Is More Than a Resume Scanner
One of the biggest misconceptions about an Applicant Tracking System is that it is simply a computer program that reads resumes and automatically rejects people.
That’s an oversimplification.
An ATS can parse resumes and make candidate information searchable. It can also support screening rules, ranking, workflows, searches, and automated actions depending on how the employer configures the system.
However, not every ATS works in the same way, and there is no universal ATS process or universal “ATS score.”
Some systems primarily function as recruitment databases and workflow tools. Others provide more advanced matching and AI-supported recommendations.
This distinction matters because job seekers often hear that an ATS automatically rejects every resume that does not contain a particular keyword. In reality, the exact screening process depends on the employer, the ATS configuration, the application questions, and other recruitment tools connected to the system.
Why Did Businesses Start Using ATS Software?
Before digital recruitment systems became common, hiring teams had to manage applications manually.
Imagine a company receiving 1,000 applications for one position.
A recruiter would need to:
- Collect resumes.
- Open each document.
- Record candidate information.
- Compare qualifications.
- Contact shortlisted applicants.
- Schedule interviews.
- Record interview feedback.
- Track rejected candidates.
- Keep documents organized.
- Prepare reports.
Doing all of this manually becomes difficult very quickly.
An ATS reduces this administrative burden by creating a structured recruitment workflow.
Modern platforms can also integrate with job boards, career pages, assessment tools, HR systems, and calendars. Workday notes that current ATS platforms can support job-board distribution, resume parsing, workflow automation, interview coordination, regulatory safeguards, analytics, career portals, and mobile access.
How Does an Applicant Tracking System Work?
Although individual platforms work differently, the recruitment process commonly follows a similar pattern.
Step 1: The Employer Creates a Job
The recruitment team creates a job description containing information such as:
- Job title
- Responsibilities
- Required skills
- Preferred qualifications
- Experience requirements
- Location
- Salary information where applicable
- Employment type
- Application questions
The employer may then publish the vacancy through the company’s career site and multiple external job boards.
Step 2: Candidates Submit Applications
Candidates complete an online application and typically upload a resume.
Depending on the company, applicants may also provide:
- Cover letters
- Portfolio links
- Certifications
- Work authorization information
- Education history
- Skills
- Screening-question responses
The ATS stores this information in a candidate record.
Step 3: Resume Parsing
Resume parsing converts information from an uploaded document into structured fields.
For example, the system may identify:
Candidate: Sarah Khan
Experience: Software Developer
Skills: Python, JavaScript, SQL
Education: BS Computer Science
Location: New York
Previous Employer: ABC Technologies
Instead of forcing recruiters to read every document from scratch, the ATS can make these details searchable.
Step 4: Candidate Screening
Recruiters can establish screening criteria based on the requirements of a position.
For example, a software company might search for candidates with:
Python + SQL + 3 years of software development experience
Another employer might require a particular certification or work authorization.
Some systems can automate parts of this process, while others primarily help recruiters search and organize candidate information.
Step 5: Recruiters Review Candidates
Qualified candidates can move to the next stage.
Recruiters may review:
- Resume
- Application responses
- Work history
- Skills
- Assessments
- Interview notes
- Communication history
This is where human judgment remains extremely important.
Step 6: Interviews Are Scheduled
Many ATS platforms connect with calendars and scheduling tools.
Instead of sending dozens of emails such as:
“Are you available Tuesday at 2 PM?”
the system may allow candidates to select from available interview slots.
Step 7: Interview Feedback Is Collected
Hiring managers and interviewers can submit structured feedback through the ATS.
For example:
| Evaluation Area | Rating |
|---|---|
| Technical skills | 4/5 |
| Communication | 5/5 |
| Problem solving | 4/5 |
| Relevant experience | 5/5 |
| Culture/team fit | 4/5 |
Structured feedback can make comparisons easier and reduce the risk of important notes being lost in email.
Step 8: Offer and Hiring
Once the company selects a candidate, the ATS may support offer management and handoff to other HR systems.
Depending on the platform, information can then flow into onboarding, payroll, HRIS, or employee-management systems.
Step 9: Candidate Records Are Retained
Candidates who are not selected may remain in the organization’s talent database, depending on company policies and applicable privacy and retention requirements.
This can help recruiters identify previously considered candidates when similar positions become available.

Why Applicant Tracking Systems Matter in 2026–2027
The recruitment environment is becoming more complicated.
Companies may receive applications through several channels while recruiting for multiple roles simultaneously. Remote work also means hiring teams may include recruiters and managers in different cities or countries.
At the same time, AI is changing how job descriptions are created, resumes are prepared, candidates are sourced, and applications are evaluated.
An ATS provides the infrastructure needed to organize these activities.
For a small company, the benefit might simply be better organization.
For a large organization, the system can become the central operating platform for talent acquisition.
