mbachallenge
I am a RD3 applicant and received an interview invite from Cornell yesterday. The last day to interview is 2/19 with the exception of the Saturday interview day on 2/27.
Congrats! Was this specific to you mbachallenge, or general for the R3 applicants? Just to allay other posters' concerns, I was told by admissions that I received one of the first interview invites for R3. I suspect most of the round's invites will be sent over the coming weeks.
Good luck all! I'm looking forward to seeing floods of acceptances on this forum.
