Suraj-Upadhye/InterviewQuest ? reverse-engineered prompt

Build me an InterviewQuest style full stack app for placement prep.

I want a student friendly site where people can browse organized study material for core CS subjects like OS, DBMS, CN, DSA, OOP, read chapter and topic based content, and take timed topic specific MCQ quizzes with instant scoring, explanations, and attempt history.

It should also have an AI mock interview feature where a user can do realistic technical, HR, or skill based interviews, including resume based or topic based sessions, with voice input and voice output if possible. After each session, show a simple scorecard with strengths, weak areas, and suggestions to improve.

Please include login with user and admin roles, a clean dashboard, dark and light mode, and an admin area where I can manage subjects, chapters, topics, study content, and quiz questions. Use React for the frontend and Spring Boot with PostgreSQL for the backend, and make the UI modern and easy to use. If you need current docs for any library, look them up online first.
