ankurdotio/interview-ai-yt — reverse-engineered prompt

Build me a simple full stack JavaScript app called Interview AI. I want someone to open the site, choose the job role or topic they want to practice for, and then have an AI interviewer ask realistic interview questions one at a time. The user should be able to type their answer, submit it, and get helpful feedback in plain English, like what was good, what was missing, and a better sample answer.

Keep a clean frontend and a separate backend that handles the AI request and keeps any secrets safe, not in the browser. Please make it easy to run locally with clear setup steps for both the frontend and backend. Add basic loading states, error messages, and a simple way to restart the interview or start a new practice session.

Keep the design modern but not complicated. If you need current AI API docs or setup details, look them up online and use the simplest reliable approach.
