I applied online. The process took 3 weeks. I interviewed at Mercer in Oct 2019
Interview
The first round is online and on-sided, you record yourself answering specific questions. The next round is in person and requires talking to the people you will be working with. Overall, Mercer guides you through the whole process extremely well and whenever I asked a question, I received very fast correspondence.
