I am interested to see what the off-campus interviews are like, as I will interview off-campus with an alumni.
So please, do share your off-campus interview experiences!
It’s pretty casual and fun. I don’t know the difference between on and off, though. (I’ve never had an on campus interview)
I live in Jamaica and did an Off Campus Interview with and Andover Alumni. They are so nice and its very casual since it’s close to home, just be open and be yourself. The interviews are really fun no need to be nervous, I’ve never had an on campus interview so I can’t make a fair comparison but i suppose they are just a friendly and welcoming 
Good luck <3
