About PrepCity
AI-powered interview preparation that adapts to your level, challenges your thinking, and gives honest feedback - just like a real senior interviewer.
Our Mission
Technical interviews are broken. Candidates spend weeks memorizing answers instead of building real understanding. Interviewers ask gotcha questions instead of evaluating genuine problem-solving ability. PrepCity fixes this by providing an AI coach that teaches through conversation, not memorization.
We believe every engineer deserves access to world-class interview coaching, regardless of their network or background. Our AI adapts to your experience level, identifies your weak spots, and pushes you to articulate your thinking clearly - the same skill that separates hired candidates from rejected ones.
