What to Expect During Your Technical Interview
The technical interview focuses on high-level system design and real-world engineering challenges rather than traditional algorithm or syntax memorization exercises. Candidates will collaborate with interviewers on an interactive system design exercise, sketching out high-level architecture and discussing modern implementation approaches. Access to an AI coding assistant (such as GitHub Copilot, ChatGPT, Claude, or similar) during the interview is recommended, as we value leveraging AI tools to solve complex system problems effectively.
