interview-coach-skill is a free, open-source interview coach for Claude Code, past 2,000 GitHub stars. You share your resume and the job post, and it runs real mock interviews, scores every answer on five things, tells you exactly what to fix, and shows you what the interviewer was thinking while you answered.
Here's what it does, how to set it up in about two minutes, and the limits you should know first.
What it does for you
- decode: reads a job post and tells you what they really want, with a fit verdict for you.
- mock: a full 4 to 6 question interview (behavioral, panel, case study, system design, bar raiser).
- Scores every answer on substance, structure, relevance, credibility and differentiation, then gives a targeted fix.
- stories: builds a bank of your best stories (STAR) and drills you to pull the right one under pressure.
- salary and negotiate: the exact words for the recruiter's salary question and for the offer.
- Remembers everything in coaching_state.md, so you can pick up weeks later.
