I applied through university. The process took 4 weeks. I interviewed at ETS (Princeton, NJ) in Feb 2013
Interview
I applied through a special program at my school. Was contacted by phone for an interview a few weeks later. It was a pretty relaxed interview, spoke with the internship coordinator, and then two departments that were interested in me. All fit/behavioral type questions, going over my resume. Everyone was very nice.
Interview questions [1]
Question 1
I think one was something like "Can you describe a time when you had a problem during group work." Can't really remember.
