LoopCoach for LeetCode

Clear the bar at your target company. A calibrated score on every LeetCode problem, Socratic hints, and the next problem to solve.

Clear the bar at your target company. LoopCoach plugs into LeetCode, measures you against your dream company's bar, then helps you clear it. Free to start. No signup. EVERY SOLVE, SCORED • A calibrated score on every problem: time, Submits, test cases and whether you landed the optimal solution. • Big-O checks versus optimal. • Interview-grade solution reviews, graded on an interviewer's rubric. COACHING LIKE THE REAL INTERVIEW • Socratic hints: a question that moves you forward, never the answer. • Ask a follow-up on any hint. • A practice journal for every attempt. MASTERY YOU CAN MEASURE • 36 topics, each rated with a modified Glicko-2, the Elo-based system family behind chess ratings and LeetCode contests. • Baseline in 1 minute: import your LeetCode history in one click. No placement test, no starting from zero. • See how ready you are for your target company, measured against the topic mix and difficulty it asks. 55 companies calibrated.
