It was a total of two rounds. The first round was a screener interview - 1:1 with a person. The next round required me to be in person and was a panel of interviews, where candidates rotated from room to room. I was interviewing with 3 other people at the same time - unlike other firms I had interviewed with.

One-on-one Screener, then callback with four interviews, two people each for twenty minutes each. Super friendly and personable interviewers, had a lot of time to ask questions. Very responsive HR and it seems like a great place to work! Withdrew candidacy after accepting another offer.
