I applied through university. The process took 2 weeks. I interviewed at Mercer (New York, NY) in Dec 2014
Interview
One over the phone interview that was predominately behavioral alongside an in office interview that was behavioral along with some technical questions. Ultimately the employer gave a background on the company and was trying to see if I was a right fit for the company and the workload.
Very easy process only one interview with two managers who were both very nice the interview was more conversational I went for an intern position in the role of a pension administrator
I applied online. The process took 4 weeks. I interviewed at Mercer in Mar 2020
Interview
One way Hirevue interview - about 9 questions that were mostly behavioral/situational.
Got an email back after 2 weeks to schedule a Zoom interview with 4 employees ranging from analyst to principal (on Zoom because of the COVID-19 outbreak, otherwise probably would have been in-person)
4 back-to-back 30 min interviews - all straightforward, common behavioral questions regarding personality and fit. Interviewers were nice and personable.
I applied through university. I interviewed at Mercer in Dec 2018
Interview
Overall a great process! Loved speaking with the team and the interview felt more like a conversation! Interview consisted of mainly behavioral questions, then there was a bit of questioning regarding how your background could help the service line.
