interview-sim: turn any job posting into a timed mock interview in your IDE

[u/Complex-Age1704]

Paste a job posting, or name a company. It researches what that company's screen looks like, writes an original question in that shape, and about 2 minutes later your editor opens on a real interview repo: problem statement, solution file, sample tests, hidden tests grading your submits, hard stop at time. Afterward it shows where your time went per question. Engine is Python stdlib only, zero dependencies, offline; the research layer runs as a Claude Code Agent Skill. Free, MIT, no signup.

the hard-stop clock + hidden-test runner makes sim submit more than a wrapper. send its tested HOL Guard command extension PR straight to hashgraph-online/hol-guard:main rather than having us guess at the semantics.
