Candidates typically go through two 45-minute technical rounds focusing on data structures, algorithms, and backend engineering fundamentals. Expect LeetCode-style medium/hard problems, system design mini-exercises, and questions about concurrency, distributed systems, and API design. Interviews may also include debugging code, walking through edge cases, and explaining tradeoffs. Strong emphasis on clean, production-ready code, clear communication, and how you reason about performance, memory, and real-world reliability. Prior experience with distributed systems, security, or blockchain concepts is helpful but not strictly required.
