I applied online. The process took 4 months. I interviewed at Oliver Wyman in Mar 2024
Interview
Two questions with two consultants both analytics based. I would recommend being very considerate of your answers and everyone in the chat room. Ask a lot of questions about the job and end every answer to the big questions with the fact you would do a linear regression model.
The process was very well structured and lasted for about two weeks. It consisted of an take home assignment, which was then discussed during an interview. Afterwards, another interview followed.
