The first-round interview was conducted entirely by AI. Other than the usual role-specific and behavioral questions, be prepared for system design questions if you're interviewing for a technical role. Talking to a camera without any real human interaction can be surprisingly challenging, especially when discussing open-ended system design topics. Without an interviewer asking follow-up questions or providing feedback, you need to structure your thoughts clearly and explain your reasoning from start to finish. If you're interviewing for a technical position, I'd recommend practicing system design answers out loud in front of a camera beforehand.
