I had interview with alumnus in hong kong, and it was pretty casual and conversational.
He asked me what I would do in next 5 years after MBA, community activity, greatest achievements, any difficult situation i dealt with at work, which is pretty generic questions you can easily expect: there is no curve ball type questions at all.
He was willing to share his MBA life at Kellogg, and the more I listen, the stronger my desire for the school.
Now I am done with everything I can do for admission with interview and part 1 and 2 which I already submitted.
And just waiting part is left until mid-Dec. phew.
