Two rounds. First round consisted of 4 interviews of 30 minutes each followed by a lunch interview. 1 technical interview, the rest was behavior and personality-based. Two weeks later I was called back for a second round of interviews, one with a senior actuary and one with a senior consultant. The interviews were alright. You had to be very quick on your feet and have a wealth of experiences to draw from (leadership, education, community work) and know the company very well. I prepped before hand for about a week, so I didn't have an issue, but I can see where interviewers may have a rough time. Everyone is extremely friendly and wants to get to know you more than anything else. Still, everyone was so friendly, helpful, and encouraging and that's ultimately what made the decision to accept the offer easy for me. Other things to note were that even though the interview process was long and I wasn't given answers when I said I would be (the company is extremely busy), I was kept in the loop every step of the way, which was very nice.
