Why Your Resume Isn't Getting Interviews

Over 98% of Fortune 500 companies use Applicant Tracking Systems (ATS) to screen resumes before a human ever sees them. ATS software parses your resume into a structured database, then scores it against the job requirements. Resumes that score below a threshold are automatically rejected.

The frustrating reality: a beautifully formatted resume with the right experience can be rejected by ATS because of a two-column layout, a text box in the header, or missing the exact keyword phrase used in the job description.

The 6 Most Common ATS Failures

  • Tables and text boxes — ATS reads left-to-right in document order. Tables break this order and produce garbled output.
  • Non-standard section headings — "Professional Journey" instead of "Work Experience" confuses ATS parsers.
  • Missing keywords — if the job description says "project management" and your resume says "led projects," ATS won't match them.
  • Contact info in headers/footers — many ATS systems ignore header/footer content and miss your contact details.
  • Graphics and logos — visual elements are invisible to ATS text parsers.
  • Saved as DOCX with tracked changes — unaccepted changes add ghost text that ATS may parse incorrectly.

How to Use the Score to Improve Your Resume

Run the checker first to identify your current score and issues. Then fix the highest-impact problems:

  1. Fix formatting issues first (tables, columns, text boxes) — these have the biggest impact on parse accuracy
  2. Add missing keywords from the job description — use the exact phrases, not synonyms
  3. Standardise section headings to match ATS expectations
  4. Move contact info to the document body, not a header
  5. Re-run the checker to confirm your score improved

Once your score is above 75, use our AI Resume Builder to rebuild the resume with optimised content and a clean ATS-safe template.

Frequently Asked Questions

The score reflects how well your resume will parse and rank in applicant tracking systems. It considers: formatting compatibility, section detection accuracy, keyword match rate against the job description, and contact information completeness.

We simulate parsing behaviour from Greenhouse, Workday, and Taleo — the three most widely used ATS platforms covering 70%+ of Fortune 1000 job postings.

Paste a job description and our AI identifies the required and preferred skills, qualifications, and experience keywords. It then checks your resume for presence, frequency, and context — not just literal matches.

Visual formatting and ATS parsing are unrelated. Tables, text boxes, multi-column layouts, and graphics look great to a human but are often scrambled or ignored by ATS parsers that read the file as plain text.

A score of 75+ is a good baseline. Scores above 85 indicate strong ATS compatibility. Below 60 typically means formatting or keyword issues that will significantly reduce interview rates.
