varalaxmi123-NU/mern_stack ? reverse-engineered prompt

Build me a full stack campus placement management system for a university. I want students, companies, and placement officers to each have their own login and dashboard, with role based access so everyone only sees what they should. Students should be able to register, browse job postings, see eligibility rules, apply for drives, upload or link a resume, and track their application status and interview details. Companies should be able to create accounts, post jobs, review applicants, update statuses like shortlisted or hired, and schedule interviews with date, time, and meeting links. Admins should have an overview of active drives, hiring stats, and institutional control. Please make it work with a React frontend, Node and Express backend, and MongoDB for data storage. Use JWT login, basic form validation, and a clean simple UI. If you need to, look up current docs online while building it.
