I applied through college or university. The process took 1 day. I interviewed at Citi (Singapore) in Apr 2014
Interview
Simple interview, met 1 on 1 with head of forex south asia, first half was more of an info session, explaining the job scope. Asked about what school was like, what interests i had, and strengths and weaknesses. Interview was around half an hour, interviewer was friendly, did not feel intimidating.
It was a really good interview process that I really liked and enjoyed doing. The first round was very casual and the questions werent challenging in the slightest. It felt low pressure or stress
They asked a mix of behavioral, technical and market questions. Pretty standard interview, no huge curveballs. There were a few brain teasers and mental math questions, no paper pen allowed.
A few rounds of group interview, some with 1 invigilator, some with a panel, and one one-to-one interview. Interviewers appeared stern and not the most friendly, perhaps to give off a sense of seriousness.
