4 rounds of interviews on-site: 3 coding and 1 system design. Each round had at least 15-20 mins focused on Leadership Principles. Coding and System Design were of medium difficulty.

Smooth and good. It was a very simple question, plus a few behavioral questions. The interview was on time, and the interviewers were super friendly. They were glad to clarify questions if I ran into any.

I was asked to interview. They called me on the telephone and requested that I solve a medium-difficulty programming question. It was about linked lists and how to reverse them in O(n) time.
