Very extensive but super fun and team oriented. It was 1-2 rounds and then if you make it to the final round it is 3 days and a total of 10 rounds of group interviews.

Great interview process, made it to the final selection. They were super upfront and communicative about the process and when candidates could potentially start. The final group of candidates had roughly 20 people, but only about half were offered. It did seem like there was some internal bias based on the percentage of the group who were interviewed and offered.
