Can recruiters tell if you keyword-stuffed your resume?

Reddit loves hidden-keyword hacks. Recruiters in the same threads say they **spot them instantly** at human review—and they kill trust.

**What ATS actually scores** Modern matchers compare semantic similarity between your experience and the JD. A skills section listing 40 tools you cannot discuss in an interview hurts both ATS trust signals and the phone screen.

**Better approach** Embed keywords inside quantified bullets: "Reduced deploy time 35% using GitHub Actions and Docker" proves CI/CD better than listing it in a cloud.

**Human read test** If a recruiter asks "tell me about your Kubernetes production experience" and you hesitate, the keyword failed. Tailor honestly with approved interventions you can defend under follow-up questions.
