Common mistakes

  • Listing every programming language ever touched instead of the 4-5 relevant to the target job
  • Describing responsibilities ('worked on', 'helped with') instead of quantified outcomes
  • Omitting scale - number of users, requests per second, data volume - that shows real impact
  • Using a functional/skills-only format that ATS parsers and recruiters both distrust
  • Failing to mention testing, code review or deployment practices, which signals engineering maturity
