Data Structures And Algorithms Interview · 60 min · Senior Software Engineer or Staff Engineer
This round focuses on your core programming skills and problem-solving abilities. You will be given one or two coding problems, typically on a shared online editor. The interviewer will assess your ability to understand the problem, devise an efficient solution, write clean and correct code, and analyze its time and space complexity. Expect questions that test your knowledge of data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, recursion).

System Design Interview · 60 min · Staff Engineer or Principal Engineer
This round evaluates your ability to design large-scale, distributed systems. You'll be presented with a high-level problem (e.g., design Twitter's feed, a URL shortener, or a real-time analytics platform) and expected to break it down, identify requirements, propose a high-level architecture, and then dive deeper into specific components. Focus on scalability, reliability, availability, latency, and consistency. Be prepared to discuss database choices, caching strategies, API design, load balancing, and potential bottlenecks.
