How ATS software actually works

Applicant Tracking Systems are software that companies use to manage the hiring pipeline. In 2026, they are common across large employers and increasingly common across mid-market teams.

What the ATS may do:

  1. Parses your resume into structured data fields
  2. Scores your resume against the job description
  3. Ranks candidates by match percentage
  4. Helps recruiters filter and search applications

Popular ATS platforms: Greenhouse, Lever, Workday, Taleo, iCIMS, BambooHR

Key insight: Each ATS parses differently. A resume that reads cleanly in one tool can still lose context in another if the formatting is too complex.

ATS-Safe formatting rules

Follow these rules to improve parsing across common ATS tools:

  1. Use standard section headings — "Work Experience", "Education", "Skills"
  2. Avoid tables and columns — Use simple line breaks and bullet points
  3. No headers or footers — Some ATS systems ignore or misread them
  4. Skip graphics and icons — They either get ignored or cause parsing errors
  5. Use .docx or .pdf — Check the job posting for format preferences
  6. Standard bullet characters — Use • or - only

Keyword optimization strategy

Modern ATS uses both exact-match and semantic matching. Here's the winning strategy:

Step 1: Copy the job description into a word frequency analyzer
Step 2: Identify the top 15-20 keywords and phrases
Step 3: Naturally incorporate them into your resume
Step 4: Include keywords in multiple sections (summary, experience, skills)

Do's:

  • ✅ Use the exact job title from the posting
  • ✅ Include industry-standard abbreviations AND full terms
  • ✅ Mirror the language of the job description

Don'ts:

  • ❌ Keyword stuff (repeating words unnaturally)
  • ❌ Hide keywords in white text
  • ❌ Use only acronyms without spelling them out

Test your resume before submitting

Avoid submitting blindly. Use these checks to validate your resume:

  1. Resumely ATS Scanner — Score with detailed feedback
  2. Jobscan — Side-by-side comparison with job descriptions
  3. Copy-paste test — Copy your resume content into a plain text editor. If it's garbled, ATS tools may struggle too
Pro Tip: Treat an ATS score as a diagnostic signal, not a guarantee. Use it to find formatting and keyword gaps before applying.

The 10 most common ATS mistakes

Avoid these resume killers:

  1. Using creative section headings ("My Superpowers" instead of "Skills")
  2. Putting contact info in headers/footers
  3. Using text boxes or tables for layout
  4. Submitting as an image-based PDF
  5. Including special characters or emojis
  6. Using two-column layouts
  7. Forgetting to include hard skills
  8. Not tailoring for each application
  9. Using uncommon file formats (.pages, .odt)
  10. Relying on a single generic resume for all applications
