Mercer Human Capital Associate interview questions

Process took about 2 weeks long. Two rounds for interview - first round consisted of two interviews, one behavioral and the other case. The case was fairly simple, it was interviewer-led and I was handed two charts to analyze and provide insight on. The second round was four hours long at the actual branch consisting of 6 interviews. 4 were behavioral and then there were two cases - one technical and one business. Overall, a pretty smooth process - everyone was very cordial and welcoming and I did not feel stressed at all.
