What Is an ATS? How an Applicant Tracking System Helps Companies Hire Faster

What Is ATS Software?

ATS (Applicant Tracking System) is software that helps companies and recruitment teams manage candidates throughout the hiring process.

Instead of managing CVs through emails, spreadsheets, or multiple disconnected tools, an ATS brings candidate information into one centralized system. Recruiters can post jobs, collect applications, screen CVs, track candidate stages, schedule interviews, collaborate with hiring managers, and analyze recruitment data from one platform.

Simply put, if the recruitment process is a pipeline, an ATS helps recruiters see where each candidate is, what needs to happen next, and which candidates may be a better match for the open position.

How Did ATS Software Come About?

Early ATS solutions were developed primarily as systems for storing and organizing resumes as recruitment processes became increasingly digital. Over time, they evolved into centralized candidate databases with tools for tracking applications and automating parts of the hiring workflow.

Today, ATS platforms can support tasks such as:

• Posting and managing job openings
• Collecting candidate applications
• Parsing and searching CV information
• Screening candidates based on criteria
• Managing candidate pipelines
• Scheduling interviews
• Sending emails and notifications
• Collaborating between recruiters and hiring managers
• Tracking recruitment data and performance

How Does an ATS Handle the Recruitment Process?

A traditional recruitment process may involve posting a job, receiving hundreds of CVs through different channels, manually reviewing each application, sending emails, and updating candidate information in spreadsheets.

An ATS helps turn this process into a more structured workflow.

1. Post a Job Opening

Recruiters can create a Job Opening in the system with information such as:

• Job title
• Job description
• Responsibilities
• Requirements
• Required skills
• Experience
• Location
• Salary and benefits

Some ATS platforms can also help distribute job postings across multiple job boards or recruitment channels.

2. Collect Applications

When candidates apply for a position, their information can be automatically added to the ATS instead of requiring recruiters to manage applications individually through email or separate files.

Candidate profiles are stored in a centralized database, making them easier to search, organize, and manage.

3. Parse and Screen CVs

An ATS can use criteria such as skills, experience, education, and keywords to help recruiters identify candidates who match the requirements of a position.

With an AI-powered ATS, this capability can go further by analyzing candidate profiles and supporting matching between candidate qualifications and job requirements.

However, the level of automation and evaluation varies between systems.

4. Track the Candidate Pipeline

Candidates can move through different recruitment stages, such as:

Applied → Screening → Interview → Assessment → Offer → Hired

Recruiters can see where each candidate is, who is responsible for the next step, and what action needs to be taken.

This becomes especially useful when a company is hiring for multiple positions or managing hundreds of candidates at the same time.

5. Schedule Interviews and Collaborate

An ATS can support interview scheduling, candidate communication, and collaboration between recruiters and hiring managers.

Instead of relying on multiple email threads or spreadsheets, everyone can work from the same candidate information and recruitment workflow.

6. Track Results and Recruitment Data

Recruitment data can be used to monitor metrics such as:

• Time-to-hire: How long it takes to hire a candidate
• Time-to-fill: How long it takes to fill an open position
• Cost-per-hire: The average cost of making a hire
• Application-to-interview rate: The percentage of applicants who move to the interview stage
• Interview-to-hire rate: The percentage of interviewed candidates who are hired
• Source of hire: Which recruitment channels generate hires

These metrics help companies identify bottlenecks in the hiring funnel instead of simply knowing whether a position has been filled.

5 Measurable Benefits of Using an ATS

An ATS does more than make recruitment workflows more organized. When implemented effectively, its impact can be measured through specific recruitment KPIs.

1. Reduce Time-to-Hire

One of the most obvious benefits of an ATS is reducing repetitive manual work.

Instead of:

Open CV → Enter information → Search candidates → Update spreadsheet → Send email → Update status again

an ATS can automate or centralize many of these steps within one workflow.

This allows recruiters to spend more time on activities that require human judgment, such as interviewing candidates, communicating with applicants, and working with hiring managers.

KPIs to track:

• Time-to-hire
• Time-to-fill
• Average screening time

Important: It is not accurate to assume that every ATS will make hiring “twice as fast.” Actual results depend on recruitment volume, workflow design, level of automation, and how effectively the system is implemented.

2. Reduce Recruitment Costs

When repetitive administrative tasks are automated, recruiters can spend less time on manual work.

Companies can also use recruitment data to understand which hiring channels generate qualified candidates and how much each channel costs.

KPIs to track:

• Cost-per-hire
• Cost by recruitment channel
• Cost per qualified candidate
• Cost per successful hire

3. Handle Larger Candidate Volumes More Efficiently

When a position receives hundreds of CVs, manually managing applications can quickly become overwhelming.

An ATS centralizes candidate data and helps recruiters search, filter, organize, and track candidates within one system.

This is particularly useful for companies that:

• Hire at high volume
• Recruit for multiple positions simultaneously
• Recruit continuously
• Have multiple recruiters
• Hire across different locations

KPIs to track:

• Applications processed per recruiter
• Average screening time
• Candidate stage conversion rates

4. Reduce the Risk of Missing Qualified Candidates

When CVs are spread across emails, spreadsheets, and different recruitment platforms, it becomes easier to lose track of candidates or fail to update their status.

An ATS creates a centralized candidate database, allowing recruiters to track candidate status and recruitment history more clearly.

KPIs to track:

• Candidate response rate
• Candidate drop-off rate
• Application-to-interview rate
• Number of candidates stuck at each stage

5. Measure and Improve Recruitment Quality

An effective recruitment process is not just about getting more candidates. Companies also need to understand which candidates are a good fit and which recruitment channels are producing them.

An ATS stores data throughout the recruitment journey, from application and screening to interviews and hiring. Companies can use this data to analyze their recruitment funnel and identify areas for improvement.

For example:

Job Board A:
1,000 applications → 50 interviews → 2 hires

Job Board B:
300 applications → 40 interviews → 8 hires

If you only look at the number of applications, Job Board A appears more productive. But when you examine conversion rates and actual hires, you gain a different perspective on the effectiveness of each recruitment source.

Which Companies Should Use an ATS?

Not every company needs a complex ATS from day one.

However, an ATS can be particularly useful for companies with one or more of the following characteristics:

Companies That Hire Frequently

If a company regularly opens new positions, managing recruitment through spreadsheets can quickly become difficult to maintain.

Companies That Receive Large Numbers of Applications

When a job receives hundreds or thousands of applications, screening automation and centralized candidate management can help reduce recruiter workload.

Companies With Multiple Recruiters

When several recruiters are involved in hiring, a centralized system allows everyone to access the same candidate information and status updates.

Companies Hiring for Multiple Positions

An ATS allows recruiters to organize candidate pipelines by job opening, making it easier to manage multiple recruitment processes simultaneously.

Companies That Want Data-Driven Recruitment

If a company wants to understand:

• Which channel brings the best candidates?
• Which positions take the longest to fill?
• Where do candidates drop out?
• How much time do recruiters spend screening?
• How is cost-per-hire changing?

then an ATS can provide an important foundation for collecting and analyzing recruitment data.

Traditional ATS vs. AI ATS: What's the Difference?

Traditional ATS platforms primarily focus on:

Store → Filter → Track → Manage

An AI-powered ATS can add capabilities such as:

Analyze → Match → Automate → Recommend → Optimize

For example, instead of simply storing a CV, an AI ATS may help analyze candidate information, identify relevant skills, compare candidate profiles with job requirements, and support recruiters during the screening process.

However, AI should be viewed as a decision-support tool, not a complete replacement for recruiters. Human judgment remains important when evaluating candidates, conducting interviews, communicating with applicants, and making hiring decisions.

Can an ATS Really Make Hiring Twice as Fast?

This is an important point to clarify.

There is no universal “2x faster” result that applies to every company using an ATS.

The impact depends on factors such as:

• Number of applicants
• Number of open positions
• Existing recruitment workflow
• Level of automation
• Recruiter adoption
• Integration with other tools

For example, a company that currently manages every CV through email and spreadsheets may save significant time by moving to an automated recruitment workflow.

On the other hand, a company that already has a highly optimized recruitment process may see a smaller improvement.

The better approach is to measure performance before and after implementation using metrics such as Time-to-hire, Time-to-fill, Cost-per-hire, Application-to-interview rate, and Interview-to-hire rate.

Some AI recruitment solutions have reported significant improvements in specific use cases. For example, Indeed has reported that its Sourcing Assistant helped some employers hire more than 30% faster. However, this refers to a specific AI sourcing product and should not be interpreted as evidence that every ATS makes hiring 30% faster or twice as fast.
