What Is an Applicant Tracking System and How Does It Work?

Ross Geller

·December 27, 2024

An applicant tracking system (ATS) is software that helps companies manage the entire recruitment process — from posting jobs and collecting applications to screening resumes, scheduling interviews, and tracking candidates through each hiring stage. Enterprise HR teams use ATS platforms to reduce manual work, improve collaboration across hiring functions, and make faster, more consistent hiring decisions at scale.

Today, over 98% of Fortune 500 companies use an ATS. For HR teams managing high-volume hiring across multiple roles, locations, or business units, it has become foundational infrastructure — not a nice-to-have.

How Does an ATS Work?

A modern ATS handles four core functions:

Job distribution — Publish openings to multiple job boards (LinkedIn, JobStreet, JobsDB, and others) from a single interface, with performance tracking per channel.
Resume parsing — Automatically extract and structure candidate information from resumes in any format, eliminating manual data entry.
Candidate pipeline management — Track every applicant through each stage: applied → screened → interviewed → offered → hired. Hiring managers and recruiters see the same real-time view.
Collaboration and decision-making — Leave structured feedback, assign scorecards, and log interview notes within the platform — no more email chains or spreadsheet hand-offs.

ATS vs. Manual Recruitment

	Manual Recruitment	With an ATS
Resume screening	Hours per role, inconsistent	Automated, structured, fast
Candidate tracking	Spreadsheets and email threads	Centralized pipeline, real-time
Team collaboration	Back-and-forth across inboxes	In-platform comments and scorecards
Time-to-hire	Typically 40+ days	Can be reduced by 30–34%
Reporting and data	Manual export, often incomplete	Real-time dashboards and analytics
Candidate experience	Inconsistent, often no updates	Automated status notifications

Key Benefits for Enterprise HR Teams

Faster hiring at scale

When you're filling dozens of roles simultaneously, manual coordination breaks down quickly. An ATS keeps every req, every candidate, and every decision in one place — so nothing falls through the cracks and hiring managers aren't waiting on recruiters for updates.

Better quality of hire

AI-powered screening doesn't just match keywords — it evaluates candidate fit based on role requirements, experience patterns, and historical hiring data. The result is a shortlist that's actually worth interviewing, not just a pile filtered by volume.

Defensible, data-driven decisions

Every action in the pipeline is logged: who reviewed which candidate, what scores they gave, when decisions were made. This creates audit trails that matter for compliance, and reporting that leadership can actually use.

Reduced cost-per-hire

By automating repetitive tasks — resume review, interview scheduling, offer letter generation — HR teams reclaim capacity. MokaHR customers report an average 36% reduction in cost-per-hire after full deployment.

5 Features to Look for in an ATS

When evaluating ATS platforms, enterprise HR teams should prioritize:

AI resume screening — Not just keyword matching. Look for systems that evaluate candidates holistically and learn from your hiring patterns over time.
Structured interviewing tools — Scorecards, question banks, and calibration workflows that make interview feedback consistent and defensible.
Analytics and pipeline reporting — Time-to-fill, source quality, funnel conversion rates, and offer acceptance trends — all accessible without a data team.
Integration depth — Native connections to your HRIS, background check providers, job boards, and video interview platforms.
Configurable workflows — Enterprise hiring is never one-size-fits-all. The ATS should adapt to how your teams hire, not the other way around.

ATS in the APAC Context: What's Different

Most ATS platforms on the market were built for US or European hiring workflows. APAC enterprise hiring has distinct requirements that generic tools often miss:

Multi-language support Hiring across Singapore, Hong Kong, Malaysia, and mainland China means job descriptions, candidate communications, and internal workflows often need to run in English, Mandarin, Bahasa, or Cantonese simultaneously. An ATS that doesn't support this creates friction at every step.

Local job board integrations LinkedIn alone isn't enough in APAC. JobStreet dominates in Malaysia and Singapore, JobsDB is essential in Hong Kong, and BOSS直聘 or 智联招聘 remain critical for China-based roles. Your ATS should distribute to these platforms natively.

Regional compliance requirements Data privacy obligations vary significantly across APAC markets. Singapore's PDPA, Hong Kong's PDPO, and China's PIPL each impose different requirements on how candidate data is collected, stored, and used. An ATS built for APAC should handle these by design, not as an afterthought.

Cross-border hiring for MNCs Many APAC enterprises hire regionally — a role might be approved in Singapore, interviewed across three markets, and onboarded in Hong Kong. Workflows that support multi-entity, multi-currency, and multi-approver processes are essential at this scale.

Frequently Asked Questions

What is an applicant tracking system (ATS)? An ATS is software that manages the end-to-end recruitment process — job posting, resume collection, candidate screening, interview scheduling, and hiring decisions — in a single platform. It replaces fragmented spreadsheets, email chains, and manual tracking with a structured, collaborative workflow.

Is an ATS only for large companies? No, but enterprise teams gain the most from ATS platforms because the complexity of high-volume, multi-role, multi-location hiring is where manual methods break down fastest. Many enterprise ATS solutions scale down for smaller teams, but the core value compounds with hiring volume.

How does an ATS improve candidate experience? Candidates receive timely, automated updates at every stage rather than waiting in silence. Application processes are streamlined, and consistent communication reduces drop-off. For enterprise employers, this directly affects employer brand perception.

What's the difference between an ATS and an HRIS? An HRIS (Human Resource Information System) manages employee data after hiring — payroll, benefits, performance, and org structure. An ATS manages the process of getting to a hire. The two typically integrate so that approved hires flow from the ATS into the HRIS automatically.

How long does it take to implement an ATS? For enterprise deployments, implementation typically takes 4–12 weeks depending on integration complexity, workflow configuration needs, and data migration scope. MokaHR's onboarding team supports end-to-end deployment with dedicated implementation resources.

What should APAC companies look for specifically in an ATS? Multi-language support, integrations with regional job boards (JobStreet, JobsDB, BOSS直聘), compliance with PDPA/PDPO/PIPL requirements, and multi-entity workflow support for cross-border hiring. Generic ATS platforms often lack these out of the box.
