I had one exam, but three research projects, one paper to show, and great communication skills. Honestly, my ability to think on my feet and my research experience are the only reasons I got it. The exam is a minimum everywhere, but you got to be able to communicate. Likewise, make your resume perfect. Also, I lived in the middle of nowhere and I applied online.
The first stage is a little particular. You're guaranteed to get the question: why do you wanna be an actuary? In fact, that was the most common question, during the entire process I was asked this 5+ times (back to back at the end). I interviewed with mike first, he asked me about recent events and tied in why actuarial science matter during the hurricane area, how would I manage staying afloat if I were an insurance company ONLY in florida. The second stage interview I interviewed with a guy whose name I forgot, we non-technical type of guy but was really a people's person. They all ask questions about your resume and how you work in groups. That's a key idea here. The next thing they'll care about is technical skills, and how you can describe what you do/did to them. The third and final stage they flew me in to Chicago. They have back to back interviews. First one for me was the technical one. I was asked what sport I like then asked how could they'd insure kind of line of insurance hole-in-one insurance for a golf course, but for your particular sport you mentioned. Then dean strolled in and really focused in on my resume, he asked me about yuwannabeanactuary, then he asked me about my research entirely, and the rest I forgot with him. Then a lady came in and asked yuwannabeanactuary, about the exam process, skills, and then we went to lunch.
The thing about the is it's still an interview. Make sure you have things to talk about, like what events would be going on in chicago that you'd like to go to, what fun things you'd like to do while there, what you liked about the interview, what you like about cna, what hobbie activities you'd do while here, where you've been, tons of small-talk-esque stuff. I actually let my guard down for a second and said "whooped a-hole [cant actually put the swear word in there]" and they both looked at eachother, meh. the rest was all right.
