I applied through college or university. The process took 1 day. I interviewed at Citadel (Hong Kong) in May 2015
Interview
Onsite interview with five people in HK office, from 9am to 3pm, they are all kind people, and asked some technical questions, and statistic question, but mainly about the resume, especially my internship experience and research work in colledge. I think my internship experience was not very valuable to them, especially to the boss. I failed the interview, and didn't get the offer, but the office seems to be great.

Start with my own self-introduction and the interviewer's self-introduction first for five minutes, then a couple of technical questions for like thirty minutes, and in the end, questions for the interviewers about the company.
I received the interview a few weeks after applying online. During the interview i was asked by the interviewer about my past experience and also some other related technical questions.
