The interviews themselves were great. Super professional and laid-back. Everyone was a joy to speak with. The process falls apart a bit in how long it took between rounds. Overall my interview process was about 3 months and ended in rejection. They seem to have high standards as the final technical round really grills you with technical problems and as far as I could tell, I only messed up on one of them despite the sheer number of questions I was asked. It took a bit for them to get back to me and I had the impression I was very close to getting the job. I did 4 rounds: HR screening, background questions from the team lead, technical interview, and a final 3-hour gauntlet of technical questions at their offices. All technical questions asked were very average, but the number of them is where the difficulty lies. It can be tiring.

phone call and then on-site for 3-4 hours. Whiteboard exercises. One on one with members of the team and then final with the VP of Engineering. Great process. Have interviewed with a number of other companies that have multiple on-site interviews which really is challenging to take that much time off and this process was much more doable. Got a great feel for the organization and what the job would be like.
