System Design Interview · 60 min · Senior Software Engineer / Architect
This round focuses on a candidate's ability to design complex, scalable, and reliable systems. Candidates are typically given an open-ended problem (e.g., design Twitter's feed, design a URL shortener) and are expected to break it down, identify requirements, propose a high-level design, and then dive deeper into specific components. The discussion will cover aspects like data modeling, API design, scalability bottlenecks, caching strategies, and fault tolerance.
