Do your homework well!
Find out more informations about your target schools.
- check out their offficial site;
-read students blog;
& you'll know many insights but you'll become more curious & automatically questions start sprouting in your mind

thats what happens with me.
Ultimately it's your dream / journey.
You might wanna know about
-culture of the school
-how much working in team is imp to sail through MBA from that particular school
-Urban / rural culture & surroundings ....+ living expenses , partying/ splurge...
the ones I have listed above are general question.
You should talk about something that you'd not know otherwise from world wide web.
Like: You should not ask 'how many studentsare from international background?' :roll: it's already there in stats page of their website. Instead you should ask how many of them actually came directly from foreign land without living in US before. You will never get such info on sites
I can come up with more questions if you need, (just reply it );
but I would leave it to individuals.
