A general market entry question and operations case interview. There were two rounds with different interviewers. The first one came to the US office from ATKearney in Germany, and I could not understand him clearly. I asked back what the question was more than twice, and everything seemed to be very tough from then. Also, I was asked about something not in other case books, so it really is required for interviewees to prepare themselves outside the box. The second interview was a guesstimation question, and finding a proxy for that question was also very tough. Since I did not pass the first screening, I was not sure what the second round was like.
