First round was a 20 minute PowerPoint presentation of a case you are given beforehand. The interviewers interrupt to ask questions and that may mess with the flow of the presentation. They ask about the maths, the solutions provided, and your thought process. They also ask about personal experience but it takes less time than the presentation

1 round phone, 2 rounds with other consultants, followed by an onsite simulation with a variety of other office teammates. 4 rounds in total. A case study will be done as well.
