Why do you want to join this B-school?
The personal interview panel might be asking you this question to check your level of interest in their B-school. You should know about the institute’s history, its flag-ship programmes, ranking, placement records, faculty members etc. It would be good if you can get in touch with a few students of that institute before your PI. Apart from giving you an idea about the kind of panel you would have to face, they can give you valuable insight into the college’s academic & extra-curricular activities.
