3 rounds back-to-back interview (30 min each, with 5 min break in between) - Structured Case - typical consulting case, with 3-4 questions, include some maths - Behavioural - a good conversation with the Principal, talking about your interests and your experience - Unstructured Case - an open-ended question, just remember to structure your answer! Interviewers are all down-to-earth and we have had great conversations. It one of the best interview expereinces so far.
