Where you go between the two won’t matter for consulting. And what kind of consulting…there’s so many nuances.
IU is a top b school and top public policy school.
You clearly would be more comfortable there. You need to want to be in the city to go to NYU.
I would say your friend going would not be reason to go. In some ways, that’s a reason not to go.
You need to be open to new experiences. Short of wanting to work on Wall Street it seems IU would be a better fit for you. Best of luck.
