Two standard case interviews with partners, back on back (final stage). Atmosphere quite relaxed, sounded more like a conversation - though of course you always have to pay attention to staying on track and delivering convincing, articulated answers. 1st case was more of a brainteaser - estimate the annual income of a taxi driver in Italy. Then a few fit questions (why BCG, why consulting, guide me through your resumé). 2nd case - Food & beverage industry, redefining the distribution strategy, a bit more complicated. Then other fit questions (most important achievement, why would hire you, tell me something that's not on your CV). Overall very positive - I joined them for an internship and the office culture is extremely informal - with lots of empowerment for newbies like me.

The online test needs preparation, simple mathematics but simple mistakes can be made, doing many samples is recommended and necessary. Did not make it to the next phase but i heard its just basic casing.
