I just had my off campus alumni interview. Pretty standard questions besides one that kind off threw me off:
What kind of mark do you want to leave at Kellogg? Caught me off guard and took me a little while to come up with an answer.
Also my interviewer asked me if I had considered the MMM program (I'm an engineer). I read on Clear Admit that they ask this question to the engineers systematically, so be prepared to have an answer

At the end she told me that I could send her an email if I had any questions. She also said to let her know what the final decision will be. I'm not sure if that's a good sign or not. Do you think that interviewers would ask that to people they don't want to recommend? Maybe, maybe not...
