System Design Interviews

System Design Interviews is now available as a separate course. If you’re actively preparing for system design interviews, this one is built specifically for interview practice.

It's a comprehensive course covering 55 interview problems, 20 technology deep dives, and 20 reusable patterns that appear across multiple problems.

If your goal is to learn system design fundamentals (and not specifically prepare for interviews), I recommend starting with the current course first.
