This topic has been addressed many, many times, but always in scattered places. And I also get differing stories. So, I thought it might be best to start a thread in order to discuss peoples' experiences / perceptions of the math questions in MBB-type consulting interviews in one place .
Some people say the cases generally involve really straightforward math (calculate the margin, profit, etc.) -- arithmetic with large numbers, basically.
I've heard other people say the math questions can be pretty complex.
The only consulting interview I've had so far involved a pretty qualitative case interview, so I haven't had a real taste of data-based interviews.
What are your experiences?
