Prepmania: an AI-Powered Mock Interview Platform for Skill Evaluation and Performance Feedback

Prepmania is an AI-powered mock interview platform designed to help job seekers prepare effectively for real interviews. The name combines "Preparation" and "Mania," reflecting a passionate, focused approach to interview readiness. The system generates role-specific questions based on user inputs like job title, skills, and experience. A key innovation is its multimodal analysis—using facial expression recognition and voice analysis to assess confidence, communication, and behavior. Prepmania enhances preparation through AI-powered feedback, response comparison, and visual performance analytics. It simulates real interviews with timed questions and tracks progress across sessions. Built with Next.js, it uses Clerk for authentication, Drizzle ORM for database handling, Tailwind CSS for UI, and Neon as its cloud database.
