The Interview, was fairly easy. They asked basic questions about your last job and situational questions. ( Such as If you were on the phone with a costumer that was upset, how would you handle the situation.)

15min hirevue with pretty base level questions, know why you want to work at Mercer. After that, 1.5 hr interview with four consultants (2 per 45 min). Lots of questions based on your past experiences, why Mercer, etc.
