Oliver Wyman Intern In Financial Services interview questions

The first was the phone interview. I was asked general fit questions plus easy case one. On the one to one case interview I was asked how to rob a bank, so firstly I considered this like a joke, but eventually it was some kind of brainteaser question. Financial Service questions are far from management ones, so the "Case in Point" is useless here. I was not able to implement any of them. I think it is useful to understand the key clients of OW in your country, since the questions will refer to these industries.
