System Design
Design a scalable and reliable software system.
This round assesses your ability to design complex software systems. You'll be given an open-ended problem (e.g., design Twitter's feed, design a URL shortener) and expected to design a scalable, reliable, and maintainable solution. The interviewer will probe your understanding of various components like databases, caching, load balancing, APIs, and distributed system concepts. Be prepared to discuss trade-offs and justify your design decisions.
