Most job seekers mirror the job posting's exact language without realizing that ATS engines also look for semantic variants. If the posting says 'revenue operations' and your resume says 'RevOps,' some systems flag it — others don't. The safest strategy: use both. Mirror exact phrases from the requirements section first, then add natural variations. Run this check before every single application and pay close attention to your job title. Title mismatches are one of the top reasons qualified candidates are filtered out before any human sees the application.
