Four stages, two of them are 2 hours long. Last stage is the one in person all before are virtual. Make sure you study the culture deck, you will be asked about it during the first 2 stages. Don't stress over the case study, you won't get info about it until 3 min before the start.

There are 4 steps to the interview process. A 15 minute video call, a 30 minute video call, and then a 2 hour case study/video call. I believer the 4th is an in person meeting with some of the higher ups, but I only made it through the first 3 before getting a standard, autogenerated sounding rejection email.
