See it in action
Questions that mirror real staff interviews
Not trivia, not algorithm puzzles. Every question puts you in a production scenario and asks you to reason under realistic constraints — the same bar a top-company loop uses.
- →Production scenario with named system, scale, and team constraints
- →Follow-up ladder — 3 rungs, Rung 1 mid-level → Rung 3 staff
- →4-dimension LLM rubric scoring on every answer
- →Expert answer + production context unlocked after submitting
Progress tracking
Know exactly where you stand
Domain breakdown, score trend, and weak-area callouts — updated after every submission. Know which domains to drill before your next loop.
- →Score trend across weeks — see your improvement
- →Weak-area callouts with avg score per domain
- →Questions attempted per week
- →Domain coverage map — spot gaps at a glance
