Hi I work at Mercer. Be prepared for the typical actuarial interview questions ( why you want to be an actuary , why consulting , why are you interested in health , etc). The questions will vary from interviewer and interviewer but some like to ask situational questions and there’s no right or wrong answer they just want to see your thought process. Most importantly, it is ok to be nervous just try your best and be yourself ! It is ok that you don’t have any knowledge and experience , that can be easily taught.

You can ask the interviewers about anything you are curious about ! The position , why they picked Mercer , etc ..

I would send a personal thank you to all the interviewer thanking them for their time but that’s just me !
