System Design Interview Framework

Why do some people ace system design interviews while others ramble for 45 minutes? You'll learn a structured five-step framework — from gathering requirements to deep diving into critical components — through real-world examples like Ticketmaster, WhatsApp, and Uber. The goal isn't to memorize solutions. It's to build a repeatable method that works for any system design problem, even ones you've never seen before.
