About this course

This course covers the core technical building blocks of system design (horizontal scaling, sharding/NoSQL, caching, CDNs, resiliency, distributed storage), a dedicated module on designing generative AI systems (RAG, agentic AI), and six full mock interviews — designing a URL shortener, a restaurant reservation system, a web crawler, a top-sellers system, a video-sharing service (YouTube), and a search engine (Google) — each with the clarifying questions, the design process, and a debrief.

The honest take: Frank Kane's background as an actual Amazon 'bar raiser' who interviewed 1,000+ candidates and held veto power over hires gives this course unusual credibility for the soft-skills side of the interview, not just the technical content — reviewers specifically cite landing offers at Google and Amazon after using this course, with one reviewer noting the mock interviews could use more question variety.
