BitHeadmr/internshala-clone ? reverse-engineered prompt

Build me a clean clone of Internshala called Internarea.

I want a simple job and internship browsing app where people can land on the home page, see available internships, search and filter them, open a listing, and view details like role, location, stipend, duration, and apply button. It should also have a basic login and signup flow, plus a way for companies or admins to post new listings.

Make it feel modern and easy to use on both desktop and mobile, with a familiar marketplace style layout. If you need to look up current docs online for anything, go ahead.

Please wire up the frontend and backend so the app feels complete enough to demo, and add a few realistic sample listings so it is not empty when I first run it.
