vijethph/PlacementCell ? reverse-engineered prompt

Build me a student placement prep portal called Placement Cell that lets students sign up, log in, and use a few helpful tools in one place.

I want a clean web app where students can watch aptitude practice videos, join a discussion forum, take quizzes, and see the latest company placement updates on a dashboard. It should also include a simple online code compiler so students can practice programming in C, C++, Java, and Python using the HackerEarth API. Make it feel like a real prep hub for recruitment drives, easy to navigate, and friendly for students.

Use a full stack setup with a React front end and a Node, Express, MongoDB back end, and keep it in TypeScript if possible. Include basic account flow, storage for user and company data, and make sure it can run locally and also with Docker. If you need to check current docs for anything, look them up online first.
