A very important reason one goes to b-school is to expand their network, meet diverse and interesting people, and learn personal and professional best practices from the diverse set of people. Right?
I want to believe the above view is represented by a large percentage of MBA students, but sadly, I am observing the complete opposite. MBA students, some very smart ones, are rarely pro-active in working with *random* group of people, or taking up assignments/projects/competitions with a group of people they have not met before.
Instead, most people just flock to others who they know well and have worked with before. In some ridiculous cases, I have seen students request re-shuffling the entire set of class study groups just so they get to work with the 2-3 students who they are comfortable with.
I wish this was not the case. Folks need to realize that uncertainty, ambiguity, and diversity all go hand in hand. One can gain A LOT from working outside the comfort zone and trying to work with people who are different and I daresay, *hard* to work with.
