Three interviews with three people in the energy practice, culminating with a partner. Mostly questions and answers, not a lot of casing. Clearly an emphasis on understanding how you think over technical skills and knowledge. Lots of boilerplate interview questions as well.

Had 3 interviews total in the final round - 1 case and 2 behavioral. They take place back to back over the course of 3 hours. One of the behavioral interviews is focused on your past experiences, the other deals more with your compatibility at West Monroe.
