System Design · 60 min · Senior Software Engineer or Architect
This round focuses on your ability to design complex, scalable, and reliable software systems. You will be presented with a high-level problem statement (e.g., designing a social media feed, a ride-sharing service, or a distributed key-value store) and expected to walk through your design process. This includes defining requirements, identifying core components, choosing appropriate technologies, discussing data models, APIs, scalability strategies, and potential bottlenecks. The interviewer will probe your design choices and challenge your assumptions.
