Grokking System Design Interview: Patterns & Mock Interviews

For a decade, when developers talked about how to prepare for System Design Interviews, the answer was always Grokking System Design. This is that course — updated for the current tech landscape. As AI handles more of the routine work, engineers at every level are expected to operate with the architectural fluency that used to belong to Staff engineers. That's why System Design Interviews still determine starting level and compensation, and the bar keeps rising. I built this course from my experience building global-scale distributed systems at Microsoft and Meta — and from interviewing hundreds of candidates at both companies. The failure pattern I kept seeing wasn't a lack of technical knowledge. Even strong coders would hit a wall, because System Design Interviews don't test what you can build; they test whether you can reason through an ambiguous problem, communicate ideas clearly, and defend trade-offs in real time (all skills that matter ore than never now in the AI era). RESHADED is the framework I developed to fix that: a repeatable 45-minute roadmap through any open-ended System Design problem. The course covers the distributed systems fundamentals that appear in every interview – databases, caches, load balancers, CDNs, messaging queues, and more – then applies them across 13+ real-world case studies: YouTube, WhatsApp, Uber, Twitter, Google Maps, and modern systems like ChatGPT and AI/ML infrastructure. Then put your knowledge to the test with AI Mock Interviews designed to simulate the real interview experience. Hundreds of thousands of candidates have already used this course to land SWE, TPM, and EM roles at top companies. If you're serious about acing your next System Design Interview, this is the best place to start.
