I applied through college or university. I interviewed at Citi
Interview
Technical Questions are easy as the interviewer will not ask you brain teasers but will look on how you structure your thoughts and how well learnt you are in your field but the interview with the sponsor is a little short. Asks some basic interview questions but you are expected to prepare a best answer in a limited amount of time. Substantial preparation is needed to excel in the interview. Knowledge of Finance is not needed but you must be very interested in technology.
