I went through a full day interview process, with 2-3 people interviewing per hour. There were logic questions, coding on whiteboard (algorithms and SQL), and design questions. There were a couple slots where it was just general questions and talking about previous projects, which was a nice break from having to code all the time. They also throw in a culture interview with the HR rep at some point in the day as well.

Standard, had to do a set of brain teaser questions within 45 minutes. Difficulty was moderate, one question was about data structures and the other was basic string manipulation. The interviewer was available for questions and guided me.
