Mercer Actuarial Analyst interview questions

The night before interviews there was a "happy hour" for those who had been selected for first round to socialize with interviewers/recruiters. they provided drinks/appetizers and were extremely nice and knowledgeable. There was not a very good ratio of candidates to recruiters though. One 1:1 interview with mostly behavioral, generic questions such as "walk me through your resume", "tell me more about this experience", "why do you want to be an actuary?", "why Mercer?", "tell me about a difficult situation", "tell me more about this extracurricular activity".etc At the end of the interview there is a case question then an excel question.
