smabdurrehmanshah/Job_Preparation_Gen_AI ? reverse-engineered prompt

Build me a full stack job preparation app where users can sign up, log in, upload their resume as a PDF, paste a target job description, and add a short self description about their background.

I want the app to analyze everything with AI and show a clear match score, the main skill gaps, a personalized study or interview prep roadmap, technical interview questions, and behavioral interview questions with helpful guidance. It should also be able to generate a polished ATS friendly resume tailored to that specific job, and let users view their previous reports later from a dashboard.

Please make it feel modern, responsive, and easy to use on both desktop and mobile. Use a React frontend and a Node, Express, MongoDB backend, with secure authentication using JWT and cookies. If you need to look up current docs or best practices for the AI or PDF handling, go ahead and do that.
