Had a phone interview and went in for an all-day interview about a month later. Took them 3 weeks to decide. Mostly typical interview questions: tell me about a time you worked in a group, tell me about a time you were really busy, etc etc. By the end of the day I had talked so much I had no idea what was coming out of my mouth. People were very nice.

First, I had a one hour phone interview with a someone on the actuarial team. The interview was involved a lot of behavior questions and discussion of my resume. Next, I had an onsite interview, which consisted of a one hour introductions to the actuarial development program, then three 40 minute interviews, and a lunch interview with two student actuaries. The three 40 minute interviews were a mix of behavioral, technical, and case study question. The process moved quickly and I heard back within a week after each of the rounds of interviews.
