Very quick (2 month start to finish). Phone screen and virtual loop. All the information is public on their website. I would suggest studying the Leadership Principals and committing them to memory.

The first round interview consisted mostly of Q+A, while the second round provided a greater overlook of Job Specifics and two preliminary LP Questions. There is a prep meeting, individual call, and "candid chat" call before the third Loop interview, which lasts multiple hours.
