As expected, after an introducton, my interviewer (a consultant) gave two case study questions. He was obviously trying to test my ability to handle pressure and distracted audiences, as he kept behaving uninterested or distracted himself. He was very understanding about my background outside of strategy consulting, however, and went through expected answers to the case studies with me very thoroughly. He was extremely polite to me before and after the interview. I did not get an offer, but it was one of the more interesting interviews. I did prepare briefly on different case interviews (but not enough) and I also made sure to smile and look confident.
