How Applicant Tracking Systems Work

When you click "Apply" on LinkedIn, Indeed, or a corporate careers page, your application doesn't land on a hiring manager's desk. Instead, it enters an automated Applicant Tracking System (ATS).

The software strips away design elements, parses your text into structured database fields (Experience, Skills, Education), and computes a relevance score by comparing your resume's terminology directly against the job description requirements.

Text Extraction

The ATS parses raw text from your document, ignoring tables, headers, and images.

Keyword Matching

The algorithm checks for exact matches with required hard skills, credentials, and software tools.

Ranking & Filtering

Candidates with a match score below the recruiter's threshold (typically 75%+) are filtered out.

Enterprise ATS Systems Compared

How the world's most popular hiring systems evaluate your resume

Workday

35% of Fortune 500

Strict keyword matching and multi-stage recruiter filters. Requires exact terminology and standard headers.

Optimization Tip: Avoid tables, text boxes, and multi-column layouts which cause Workday parsers to misread chronological order.

Greenhouse

Top Tech & High-Growth Startups

Combines algorithmic keyword extraction with structured scorecards for hiring managers.

Optimization Tip: Emphasize measurable impact (e.g., "Increased revenue by 34%") and prioritize relevant technical competencies.

Taleo (Oracle)

Enterprise & Government Agencies

One of the oldest and strictest ATS platforms. Assigns percentage match scores based on resume density.

Optimization Tip: Use standard section titles like "Work Experience", "Education", and "Skills" rather than creative labels.

Lever

Modern Tech & Mid-Market Firms

Focuses on candidate relationship management and fast semantic parsing.

Optimization Tip: Ensure your resume uses clean UTF-8 text formatting and standard bullet points.

The 5 Golden Rules of ATS-Friendly Formatting

DO: Use clean, single-column chronological layout

AVOID: Use multi-column layouts, tables, or sidebars

DO: Save as PDF or DOCX with text selectable

AVOID: Upload flattened scanned image PDFs or PNGs

DO: Use standard headings (Work Experience, Skills, Education)

AVOID: Use unconventional headings (e.g. "My Journey", "What I Do")

DO: Include both acronyms and full terms (e.g. AWS & Amazon Web Services)

AVOID: Assume the ATS parser knows industry shorthand automatically

DO: Quantify achievements with metrics (%, $, numbers)

AVOID: List generic job descriptions without measurable impact

Frequently Asked Questions About ATS Resume Checkers

What is an ATS (Applicant Tracking System)?

An Applicant Tracking System (ATS) is automated software used by over 98% of Fortune 500 companies and 70% of growing businesses to organize, scan, and rank incoming job applications before a human recruiter ever sees them.

Why do resumes fail ATS screening?

Resumes most commonly fail ATS screening due to missing crucial job keywords, complex formatting (tables, graphics, headers/footers that parsing software cannot read), or lack of quantified experience aligned with the job description.

Is PDF or Word (.docx) better for ATS systems?

Both PDF and DOCX are widely supported today, provided the PDF contains selectable text (not a scanned image) and does not use complex multi-column grid layouts.

How does ATSResumeScan help me pass the ATS?

ATSResumeScan runs your resume through the same parsing heuristics used by Workday, Greenhouse, Taleo, and Lever. It identifies missing keywords, flags structural formatting bugs, and uses AI to rewrite your bullet points for maximum keyword alignment.
