Hi Anonymous A,
thanks for asking your question on our Consulting Q&A :)
I found an old Q&A that might be interesting for you. It is not particularly about the phone interview with Oliver Wyman, but with McKinsey. Here are the experiences two of our users share:
- The case has the same kind of structure as a normal McK interview, but without graphs since it’s via phone. So the interviewer will give you the case problem (in my case it was market entry) and you have to approach it like you would a normal case, so first of all elaborate your structure how to approach it (issue tree). You will have to do some calculations, but they are really not so difficult. And then at the end you have to give the recommendation and support it with the arguments as the closing statement, also including risks. As you see it’s really like the normal kind of case but simpler I would say. It is a bit weird not being face to face to the person, so maybe practice as well such kind of setting to get used to it. Hope it goes well!
- its cake. it will be given by a mckinsey alum, and is typically going to be one of the simplest cases you'll ever do... probably simpler and quicker than any of the ones here. its simply there to weed out people who aren't going to advance early in the process without going through the trouble of flying them out, having current managers talk to him/her, etc.

I hope this is helpful for you!
Best of luck for your interview!
