I had my interview in London last week - very much enjoyed the process. There were two interviewers who made me feel comfortable from the very first moment. As many already posted it is hard, to impossible prepare the answers.
The conversation was retrospective, the interviewers seemed to be little interested in my goals for and after the MBA. There were several deeper questions about the experiences I mentioned in the application form, but for the rest they were building up the questions on my answers. I think it was particularly important for them to clearly understand what I had to say e.g. they would ask clarifying questions like the following: in a particular experience you described, why in your opinion the person handled in this way, how would you act if you were in that situation yourself, what did you learn out of it?
All in all I have the feeling that in the interview I was given a chance to present myself at my best, in some way it might also be a strategy to ensure comparability of the candidates.
As many others I am joining the second round of the wait game now!
