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.
Interview questions [1]
Question 1
You have 99 distinct numbers from 1-100, how would you find which number is missing?
The process took 1 day. I interviewed at Citi (New York, NY) in Oct 2010
Interview
Had a face-to-face interview on campus. Invited to their Superday interview held at their New York office. Had 8 rounds of interviews. Got questions including maths, programming, logic, finance. Tough interview. You need to learn really a lot to prepare for the interview and more importantly, you have to sell yourself and make them like you. Did not get the offer.
I applied online. The process took 2 days. I interviewed at Citi (New York, NY) in May 2010
Interview
they responded very quickly. actually two short phone calls about background, no actual technique stuffs. then ask you to finish an online test of C++ and math. for c++ I got 32 out of 36, (which I guess failed me for), 23 out of 24 on math.
