N.O.V.A.: An AI interviewer that teaches you when you get stuck

Hey Product Hunt! 👋 I'm a final-year engineering student from India, and I built N.O.V.A. because most interview prep either throws hundreds of questions at you or grades your answer without helping you understand what you missed. What N.O.V.A. does: • Adaptive mock interviews: follow-up questions change based on your answers • "I don't know" mode: instead of just marking you wrong, it teaches the concept (explanation, example, diagram, interview-ready answer) and lets you retry • Feedback on accuracy, completeness, clarity and reasoning • Timed online assessments, coding and SQL labs, and system design practice • A readiness score, weak-topic tracking and a daily study plan I'd love your honest feedback, especially on how useful the explanations feel when you get stuck. What would make you come back to it?
