GrindQuestionsAI covers the concepts that come up in real senior-level technical interviews. Every question is open-ended — you type your explanation in your own words, and AI grades it against expert-defined criteria.
Questions range from foundational concepts ("What is the CAP theorem?") to senior-level depth ("Explain the tradeoffs between Raft and Paxos for consensus"). The AI evaluates whether your answer demonstrates real understanding, not just keyword matching.
Most interview prep is cramming — study hard for a week, forget most of it within days. GrindQuestionsAI uses spaced repetition scheduling (the same science behind medical school flashcards) to review concepts at the exact moment you're about to forget them.
Questions you answer correctly get scheduled further out. Questions you struggle with come back sooner. Over time, you build a durable knowledge base that survives weeks and months — not just the night before.
Self-study has a fundamental problem: you don't know what you don't know. You read your answer, think it sounds right, and move on — missing the gaps that an interviewer would immediately probe.
AI grading catches those gaps. Score a 2/3 on explaining database sharding? The feedback tells you exactly what was missing — and a follow-up question probes that specific gap. It's like having a senior engineer coaching you through every question.
Track your pass rates, retention curves, and weakest domains over time. See which topics need more work and which you've mastered. The analytics dashboard shows card states, upcoming review workload, review history, and interval distribution — so you know exactly where you stand.
