Understanding Applicant Tracking Systems (ATS)

Learn how ATS works and why it matters for your job search success

What is an ATS?

An Applicant Tracking System (ATS) is software used by over 99% of Fortune 500 companies and 75% of all employers to manage their recruitment process. These systems scan, parse, and rank resumes before they ever reach human eyes.

When you apply for a job online, your resume typically goes through an ATS first. The system extracts information, searches for keywords, and assigns a score based on how well your resume matches the job requirements.

How ATS Works

  1. 1
    Resume Parsing

    The ATS extracts text from your resume and categorizes information into fields like work experience, education, and skills.

  2. 2
    Keyword Matching

    The system searches for specific keywords from the job description and counts how many times they appear in your resume.

  3. 3
    Scoring & Ranking

    Your resume receives a score based on keyword matches, relevance, and other criteria. Higher scores rank higher in search results.

  4. 4
    Filtering

    Recruiters can filter candidates based on specific criteria, and only top-ranking resumes typically get reviewed.

Common ATS Pitfalls

Things That Hurt ATS Parsing

  • • Complex formatting and graphics
  • • Tables, columns, and text boxes
  • • Headers and footers
  • • Unusual fonts or symbols
  • • Images or scanned PDFs
  • • Incorrect file formats

ATS-Friendly Practices

  • • Simple, clean formatting
  • • Standard section headings
  • • Chronological work history
  • • Keywords from job description
  • • Standard fonts (Arial, Calibri)
  • • PDF format

Optimizing for ATS

Use Keywords Strategically

Include exact keywords and phrases from the job description naturally throughout your resume. Don't keyword stuff—use them in context.

Format for Readability

Use standard section headings like "Work Experience," "Education," and "Skills." Avoid creative headings that ATS might not recognize.

Include Both Acronyms and Full Terms

Write both "Search Engine Optimization (SEO)" to ensure the ATS catches either version.

Quantify Achievements

Use numbers and metrics. ATS systems often look for quantifiable results as indicators of performance.

The Human Touch Still Matters

While optimizing for ATS is crucial, remember that your resume will eventually be read by humans. The goal is to create a resume that:

  • Passes ATS screening with high scores
  • Remains compelling and readable for human recruiters
  • Tells your professional story effectively
  • Demonstrates your value clearly and concisely
