I submitted my application few days before the deadline and still was not contacted for interview. Should I contact them?
No.
If they don’t offer you an interview, then that could mean that there are not enough alumni to interview all of the applicants from your region. Columbia will not punish you if you were not offered an interview.
For what it’s worth I have not gotten an interview yet either.
Don’t they offer alumni interview?
I’m an international student and I had my interview on Skype with an alumni a few days back. I wouldn’t suggest sweating over it. It’s not like they’re selective or something
Not all admitted students get interviewed, do not worry about it.
