I have a case interview with pwc's Deliverig Deal Value team. Can somebody please brief me on what to expect?i.e. is it likely to be:- a very Operations-based case- a general, more strategic business case- brainteaser type Qs...?Many thanks in advance.

There are several case studies based on different industry sectors and the area you're applying to (ops/IT/PMI etc). In general terms, they are based around a real-life deal scenario with all of the elements you mention below reflected (including some numerical analysis).
