Hi, I have received my third case interview invitation at BCG (principal level). Does anyone know usually how many interviews will there be? Also, I'd like to seek some advice on the preparation for principal & partner level interviewers. I've heard that final rounds become more unstructured and flexible, and sometimes there's not even cases but brain teaser questions instead. I've practised 50 cases up to now, but would like to know how to strengthen myself for the last rounds of interviews. Would appreciate hearing some advice!
Thank you!! For the final rounds, is it always partners interviewing? hank you!! For the final rounds, is it always partners interviewing? Or it could be also principals?
