The process took 1 day. I interviewed at Columbia University (New York, NY) in May 2011
Interview
This was easily the most useless and unprofessional interview I have ever had. The interviewer was completely unprepared and didn't even have a computer for the Powerpoint presentation he asked me to prepare - something I spent days working on. In addition to that, I was asked absolutely no questions relevant to my job experience. I was not even given any feedback except for some highly unprofessional comments about my lack of time-management skills due to the fact that I went overtime on my presentation. (So sorry about that, by the way. Next time I give a Powerpoint presentation WITHOUT a computer and no way to time myself, I'll try to be more in touch with my internal clock!). I also thought it was rather ironic that the guy calling me out on my "time management skills" was at least 10 minutes late for the interview and also didn't even stick to the timeline he gave me concerning when I would hear back about the position. By that point, I realized this whole interview was a joke and that they never had any intention of considering me as a serious candidate. I could go on and on but I will stop there.... Ultimately, I can't imagine that this "interview" (if I can even call it that?) is indicative of the overall experience at Columbia, but it was nevertheless my experience. It was a huge disappointment and a massive waste of my time and resources. Don't let these jokers give you the run around.
