I applied through college or university. I interviewed at Columbia University
Interview
The interview was a first round phone call. Discussed my background, what I hoped to gain, and nature of the internship. There were two current fellows who interview me. Was told that they would get back to me in ~2 weeks.
Interview questions [1]
Question 1
Tell us a little about your resume? What do you hope to gain? What do you look for in a superviser?
I applied online. The process took 4 months. I interviewed at Columbia University
Interview
Extremely slow moving (4+ months). Expensive with no assistance even though they require on campus interviews. They do a phone screen, in person committee, and then some type of one on one interview
