Two behavioral interviews and one case interview. The first two interviews were very friendly and conversational, the case was slightly more serious/less friendly. Overall, a wonderful company and interview process. However, the whole process did take a long time. From the time I applied, there was about five weeks until I heard back about getting an interview, then another week until I had my second and third. I didn't receive my offer until 6-7 weeks later, though.

Interview consisted of two behavioral and one case study. Whole process took a month. Very engaging and fair process. Would recommend to a friend as there was good communication and feedback throughout the process.
