What Is ATS Scoring?

An ATS (Applicant Tracking System) is software used by recruiters and hiring managers to filter, parse, and rank resumes before they reach human eyes. Over 98% of Fortune 500 companies use ATS systems to manage high volumes of job applications.

Your ATS score is a numerical rating (typically 0-100) that reflects how well your resume can be parsed and understood by these automated systems. A higher score means:

Your resume structure is clear and machine-readable
Section headers are properly recognized (Experience, Education, Skills)
Keywords match the job description
Formatting doesn't break automated parsing (no tables, headers, or images)
Contact information is correctly extracted

Why ATS Matters for Job Applications

75% of resumes are rejected by ATS before a human ever sees them. Even if you're perfectly qualified, poor ATS compatibility can eliminate you from consideration automatically.

Common reasons resumes fail ATS screening include:

❌ Formatting Issues

Complex layouts, tables, images, headers/footers that ATS can't parse

❌ Missing Keywords

Lack of industry terms, job-specific skills, or exact phrase matches from the JD

❌ Poor Section Labels

Creative headers like "My Journey" instead of standard "Experience"

❌ Unreadable File Types

Image-based PDFs, unusual fonts, or incorrect file encoding

Common Resume Parsing Issues

1. Complex Formatting

Multi-column layouts, text boxes, and tables confuse ATS parsers. They may read content out of order or skip sections entirely. Stick to single-column, top-to-bottom flow.

2. Non-Standard Section Headers

Use conventional headers: "Work Experience" or "Professional Experience" instead of "Career Timeline," "Education" instead of "Academic Background," and "Skills" instead of "Competencies."

3. Graphics and Images

ATS cannot read text embedded in images, logos, or charts. Keep your resume text-based. Avoid decorative graphics, profile photos (unless required), or skill bars rendered as images.

4. Incorrect File Format

Always submit .docx or plain-text PDFs unless instructed otherwise. Scanned PDFs (image-based) are unreadable by ATS. Test your PDF by trying to select/copy text — if you can't, neither can the ATS.
