I applied online. The process took 1 day. I interviewed at Columbia University in Feb 2008
Interview
I met with 4 professors, and each of them spent an hour asking me questions regarding my background in science. They clearly expected me to be able to describe experiments that I have done in the past and put emphasis on the rational of my experiment design and ability to reason.
They are all very nice, and some of them spent more time telling me about their research than asking me questions.
Interview questions [1]
Question 1
Why didn't you do well in that course (you got a C)
I applied through the Columbia University federal work study job posting site. I interviewed and received an offer shortly after. The interview was short and typical. The process was simple and easy.
Very encouraging and fair. I was asked relevant questions to my degree. My advisor provided me clear expectations for my program. I was asked questions related to DSP and ML.
I applied through college or university. I interviewed at Columbia University (New York, NY)
Interview
Interview with project coordinator. Will ask about your previous research experience and why you are interested in the study. Usually one to two interviews, depending on the study and position.
