What trips up an applicant tracking system
Before anyone reads your resume, the ATS pulls the text out of your PDF and files it: name, contact details, jobs, dates, skills. If the text comes out empty, scrambled or full of symbols, the profile it builds is wrong, and a recruiter's search for your skills can miss you.
The usual causes: a scanned or image-only PDF (there's no text to read), icons and fancy fonts that come out as symbols, two columns or tables read straight across, contact details only inside a header picture, and creative section names where a parser expects Experience, Education and Skills.
The fix is plain: one column of real text, standard headings, your email and phone written out, and each role with its years. Then use the words of the job where they're true.
