Yep, it's called Coding Interview University. Ah yes, the I can't afford a CS degree starter pack. What's inside it? A complete self-study plan covering data structures, algorithms, operating systems, networking, databases, system design, basically everything taught in a computer science degree. Hold on, all in one repository? All in one place. The creator built it for himself while preparing for software engineering interviews. Incredible, humanity uploaded four years of academic suffering to GitHub. So people actually use this? Constantly. It's one of the most famous learning roadmaps on GitHub for aspiring software engineers. And it's completely free? Completely free. Beautiful, somewhere a university brochure just burst into tears.
