I won't say that the sheet doesn't contain misinformation (its crowdsourced so literally no way of knowing)
But I will say that Columbia DID send out invites in fact. I got one earlier this week (neurobiology and behavior program)
May i ask what the interview dates are? I didnt get invited ? but if by grace of god they do another round of invites, i'd like to make sure I dont block their weekends...
