Applicant Tracking Systems are not magic — they are pattern-matching parsers. Workday, Greenhouse, Lever, Taleo and SuccessFactors each ingest your file, extract tokens, and score them against a job description. Most resumes fail before a recruiter ever opens them because of three repeatable mistakes: non-parseable formatting (columns, text boxes, headers/footers, graphics), missing semantic keywords, and weak section labeling. An ATS-optimized resume uses a single-column flow, standard headings, file-native fonts, plain text bullets, and keyword density calibrated to the target role. Done correctly, the same candidate can move from a 41 score to 98 without changing a single underlying fact about their career.
