I had a phone screener with a recruiter, followed by a one-hour technical phone interview. After that, I attended an onsite interview that lasted approximately four and a half hours.

The onsite included interviews with four different people. While they were all nice and supportive, one interviewer stood out. The first three conducted algorithm-based interviews, and the last person asked me to describe a problem I encountered in a previous job in depth.

Tree path question. Some graph BFS. Pretty simple stuff.
