Mercer Actuarial Intern interview questions

Got a referral and got a phone interview weeks later. The questions consist most of behavior questions. No standard questions at all. No question like talk about your self or why you want to work at Mercer. The interview is harder than expected. Mercer seems to very care about hiring intern. It considered its intern as future full-time staff.

After submitting my resume I had a panel interview with 2 employees. They were very kind, informative, and made the processes very comfortable. Within a few weeks they notified me that I would progress to a second round interview. They arranged for my stay in a very nice hotel suite adjacent to the office building since I was traveling several hours for a half day of interviews. I interviewed with three separate individuals, and a panel of two employees over a lunch that they covered. I wasn't asked any skills testing questions, but instead they asked personality questions and allowed me to ask a lot of questions.
