Tsiona23/Interview-Hub- ? reverse-engineered prompt

Build me a clean, modern interview prep website called Interview Hub for students and job seekers.

It should have a home page plus separate Study, Practice, and About pages, all with a consistent responsive design that looks good on desktop and mobile. The Study area should let users pick an interview category, choose how many questions they want, and read the questions with clear answers and explanations. The Practice area should generate quiz style questions from selected categories and let users choose the number of questions so they can keep practicing. Use the interview content from a JSON data file, and make it easy to add more categories later, like web development, cloud, DevOps, databases, programming, and similar topics.

Please keep the UI polished, simple to use, and include smooth transitions and nice visuals. If you need to check anything about current best practices or browser behavior, look it up online first.
