Hi,it depends a lot on what stream / concentration you intend to choose (e.g. Strategy, MIS, Finance etc.).
Most of the interview will center around your work, why you chose Katz etc. And then based on your desired concentration, they will ask you different questions. Folks who apply for the MIS concentration are typically handed a case study. In my case, the interviewer asked me about the Trans Pacific Pact as I was interested in Strategy.
All the best for your interview. Hope you ace it.
