Note: I truly think Mercer is a great company that I would love to work for despite my experience. I can tell the people that work there are genuine and caring; which is rare. General Process: Submit online application and recruiters at corporate will sift through the applicants. If they like you then HR calls you and schedules a phone interview. They usually do a few phone interviews, aptitude test(s), then an in person interview or HiVue interview if you're remote. This was a 2 hour interview with 4 interviewers having a budgeted 30 mins with each applicant. I wonder the effectiveness of jaded interviews. Those who interview are not actually recruiters, so they have a bunch of other responsibilities they need to get to... I imagine they want to do things that help them keep their job moreso than focus on an applicant trying to answer a question correctly. My experience: The process lasted 3 months. I was a referral from a respected employee and enjoyed visiting with the employees I interviewed with. The high level of ambiguity during the interview process was difficult. Long story sort, I made it to 2 final round interviews (the latter interview suggested after the original final round interview). HR sent me emails to links with the wrong job description attached so I literally was not sure what job I was interviewing for since different emails were saying different things. Mercer was impressed enough for me to be a "runner-up" to a senior position that they would move me to an entry level position to gain a proper foundation. I loved this about them! However I found it odd that they would not seek clarification of my responses to their questions nor give me any feedback after denying me twice.
