I applied through college or university. The process took 2 weeks. I interviewed at Citi in Oct 2010
Interview
Initially two phone interviews 30 mins each with quantitative questions in each one. Then was flown out to New York for Superday and had 8 interviews 30 mins each that day with a math test in the morning. If flying from the west coast, it's important to plan so your schedule is not messed up when you have to wake up at 6am EST for your interview. Do not make my mistake and sleep 5 hrs a night for the entire week before the interview.
