I can tell you which were some of the cases from last year's recruiting process:
1º Price football tickets for an Southafrican team (You had to price them and create an strategy that would fit in the country, you must know the special situation of Southafrica for this one)
2º Price a factory (for a selling purpose) which creates an unlimited supply of milk (Understand the market and go for a DCF)
3º Market sizing of tombs in Slovenia (Pretty standalone, just getting to a number, not much explanation)
Then there are like 10 mins of fit part in each interview
Overall its a simple process, but you will be challenged by interviewers that are not consultants, but rather clients of the firm (I had a Russian interviewer) and there are some brainteasers too.
*** BTW: There's usually a GMAT test over skype as a screening process
