Phone technical, very easy. They asked me the "underground train" question, which they apparently ask a lot, but I didn't know it and still found the interview simple.

In-person technical, not too hard a problem (not very LeetCode-y) that they slowly built on as time went. Just know your basic DSA knowledge.

In-person system design. As a student, they don't expect you to know a lot of specialized book knowledge. I was given existing architecture and asked about how I would implement some features in it.

HR, general HR and situational questions about previous teams, etc. I slipped up by saying I enjoyed data science.

Underground train system (google it) Training a "next word" prediction model on frequency counts Implement logging/warnings on an existing system
