An interview process similar to other large companies who hire actuaries. This was a scheduled interview day from 8-3, where I was interviewed by 6 more experienced Actuaries in the department. I was also given a math aptitude test (which tested your ability to do basic math in your head), and a test to see if you understood the basic concept of pensions. There was generally no break, however we had lunch with 2 younger analyst who we casually chatted with and talked about the job (and many other things). Overall a good interview experience. For someone who hasn't done it before, the all day interview may seem daunting, but while it is exhausting, it is also less nerve racking than a single high pressure interview. The interviewers have a few standard interview questions to ask you, but for me they felt more like good conversations for an hour each.
