For those who've applied/attended top-3 b-schools...
What do you wish you would have done differently at the start of your career, in order to better optimise your top-3 b-school applications/experiences?
Are there things you found out later that were important, but years ago you hadn't really paid enough attention to? Wish you had gotten more involved in extracurrics, or community involvement outside work?
If you could go back to before the application process and change your behaviour in some plausible way, how would you change it?
