I applied online. The process took 2 days. I interviewed at Citi (New York, NY) in Feb 2010
Interview
Just went through 1st round, had 2 interviews with 1 person each time on the trading floor. Very fit oriented, didn't receive any technical questions. Interviewers were traders/sales traders so they were also pretty busy at the time. Each lasted half an hour, though my 2nd one was cut a little short.
Interview questions [1]
Question 1
What makes you different than the other 100 kids I will interview? (Why should we pick you)
