Well, MIT for that matter does not have internship in their year long curriculum, and they have been able to place international ppl with zero work experience.
Columbia does not publish their stats, so we dont know. But, i heard, ppl can fit internship in their curriculum if they choose to graduate in August. Have basically seen mixed responses on this issue. Very unfortunate, that a so-called ivy league b school does not clarify how many ppl were actually able to secure internships before the term ends
