The whole process took about 4 weeks where myself and several ivy leagues were being scheduled from interview to interview by an intern. The intern was our point of contact if we needed anything. Overall they asked a lot from us with pre-calls and post calls as well as a full interview day that lasted several hours. After the interview I heard nothing. I reached out several times and finally after several weeks received a not interested email. Turns out that all of the candidates received the same email.
