You pick a question, then have a real-time voice conversation with an AI coach powered by ElevenLabs. The coach asks follow-ups, probes your reasoning, and offers hints when you're stuck — just like a real interviewer.

You're scored across multiple axes: Conceptual Understanding, Applied Reasoning, Communication, Problem Exploration, System Architecture, Technical Depth, and Trade-off Analysis. Every score includes evidence quotes from your actual transcript.

11 domains: Recommendation Systems, Search & Ranking, Fraud & Anomaly Detection, NLP & LLMs, Computer Vision, Content Moderation & Safety, Ads & Click Prediction, MLOps & Infrastructure, Generative AI, RL & Decision Systems, and AI Agents & Tool Use. 200+ questions across 3 difficulty levels.

We're voice-first (not text chat), ML-specific (not generic CS), focused on production-scale systems (not toy problems), and we coach you (not just grade you). Every piece of feedback quotes your actual words.

We're designed for mid-career engineers (2-8 years) transitioning into ML/AI roles. Easy-difficulty questions (3-5 min) are great for building foundations, while Hard questions (15-25 min) simulate full system design interviews.

A library of 10+ skill categories (ML Fundamentals, Deep Learning, MLOps, etc.) with overviews, curated video resources, interactive quizzes, and progress tracking from Learning to Mastered.

Yes. The Learning Hub dashboard shows interviews completed, skills mastered, average scores, and domains practiced. You'll see your top strengths, weak areas, and personalized recommendations for what to practice next.
