What Is an ATS?

Understanding the software that stands between your resume and a human recruiter is the first step to landing your next role.

What Does ATS Stand For?

An Applicant Tracking System (ATS) is software that automates the recruitment and hiring workflow-from job posting to offer acceptance. It functions as both a database and workflow engine: collecting applications, parsing resume information, screening candidates, scheduling interviews, facilitating team collaboration, and generating hiring analytics.

97.8% of Fortune 500 companies use an ATS, with Workday commanding 39% of the enterprise market.

How Does an ATS Work? Step-by-Step

1. Job Posting and Application

Recruiters create job postings directly within the ATS, which automatically syndicates to multiple job boards (LinkedIn, Indeed, company website). Candidates apply through the career portal or email their resume. The ATS immediately logs the application and assigns a status.

2. Resume Parsing: Extracting Data

When a resume uploads, the parsing engine automatically extracts structured data: Name, contact info, work history, titles, education, skills, and certifications. This eliminates hours of manual data entry prior to how ATS read files.

File Format Accuracy

FormatSuccess RateWhy
Plain text .docx~96%Cleanest extraction
Standard .pdf~85%Works well if not image-based
.docx with tables~31%Tables confuse parsers
PDF with embedded fonts~18%Font encoding breaks text
Image-based PDF~0%Cannot extract any text
Heavily designed resume~10%Graphics break parsing

A study of 1,000 resumes showed that 23% of ATS rejections were formatting failures, not qualification mismatches.

3. Screening and Ranking

Based on recruiter-set criteria (skills, years of experience, location, certifications), the ATS: Ranks candidates by match score, filters top candidates first, and auto-answers knockout questions. This is how ATS score relevance.

92% of recruiters use ATS to rank and sort candidates-not to auto-reject them.

4. evaluation and Search

Recruiters actively search the candidate database by keywords, job titles, or skills. Modern ATS systems highlight top matches, but recruiters examine deeper candidate records.

5. Collaboration

The hiring team leaves interview notes, ratings, and feedback directly in the ATS, creating a collaborative evaluation process.

Proprietary / In-House ATS

Amazon, Apple, Tesla, Uber, Bloomberg, and Shopify built their own. The catch: these systems rarely expose a standardized candidate portal, application status is often invisible after submit, no email updates, no progress bar. This is exactly where an external Application Tracker (like JobMentis's) becomes essential to know where you stand and when to follow up.

What an ATS Does NOT Do (Debunking Myths)

Myth #1: 'ATSes Auto-Reject 70–75% of Resumes'

The Reality:This is folklore. Data shows only 8% of recruiters use hard auto-rejection. 92% use ATS to rank and sort, and 90–95% of applications are viewed by humans. See more common myths.

Myth #2: 'ATS Cannot Understand Context'

The Reality:Modern ATS use semantic search and AI to understand synonyms (e.g., 'Marketing Manager' = 'Growth Lead'). However, only 34% of systems support full semantic recognition.
