aasthas2022/SDE-Interview-and-Prep-Roadmap ? reverse-engineered prompt

Build me a clean, easy to use interview prep roadmap page based on this checklist.

I want a simple site where I can browse all the main interview topics, like data structures, algorithms, system design, operating systems, networking, databases, programming basics, testing, security, version control, and behavioral prep. Each section should open into a readable checklist with nested topics, and I should be able to check items off as I study. Keep it organized and calm to look at, something I can actually use every day while preparing.

Please also make it feel like a polished learning resource, with a clear home view, easy navigation between sections, and a way to open or download the printable PDF version too. If anything in the repo needs updating, go ahead and improve the wording and layout so it feels complete and helpful. If you need to look up current docs online for the best way to do it, that’s fine.
