The process took 1 day. I interviewed at Mercer (Chicago, IL) in Feb 2011
Interview
Applied through university career center, and had an on campus interview. The interviewer mainly asked about my resume/ strengths and weaknesses. Also asked why do you want to work at mercer and why do you want to do consulting. The interviewer also asked some personality questions and spent a large amount of time describing what the position entailed.
I applied online. I interviewed at Mercer in Nov 2022
Interview
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.
I applied through college or university. I interviewed at Mercer (Houston, TX) in Jan 2021
Interview
Interviewed with the Houston office. First round hirevue, then advanced to the superday. 6 back to back interviews. Overall it was pretty behavioral. There were some Google questions that kind of threw me off
The first round was a timed video interview with a number of questions. The video was one-way with automated questions that you can read and have a certain amount of time to answer.
