abhinavv016/IntervueX ? reverse-engineered prompt

Build me a full stack app called IntervueX with a clean frontend and a backend that work together smoothly.

I want it to feel like an interview practice tool, with a simple landing page, a place to start or join an interview session, and screens for answering questions and seeing basic feedback or results. Keep the design modern and easy to use, with clear navigation and a polished UI.

Set up the frontend and backend so they talk to each other properly, and make the app feel ready to run locally without a lot of manual setup. Use good defaults, clear structure, and sensible error handling. If you need to check current docs online for the best way to wire things up, go ahead.

Please make sure the whole thing is complete enough that I can open it and understand how to use it right away, with sample data or placeholder flows where needed.
