hi ms,i actually went through the exact same situation as yours, a science major (physics) interviewing with bain in munich.you will have three interviews, one fit-based with a small case (~15 min.), and then two more extensive cases, one of which will be conducted in english.as far as the cases go, it is similar to what you would encounter elsewhere as well. market sizing, profitability yadayada ...that being said, i found the whole interview process enjoyable, more so than at bcg and mck. the dedicated fit-interview can only work for your advantage as an exotic, you really can show them that you are serious about consulting. they believe you are smart enough anyways, otherwise they would not have invited you, but i believe they value if you can present yourself with sincerity and maturity and know what you're getting yourself into. don't try to dazzle the interviewer, make it clear that you know it is a hard job and that you are looking forward to the training they can offer you with your non-business background.cheers, andy
