Financial Technology Associate Intern Interview

Financial Technology Associate Intern
Chicago, IL

I interviewed at Citadel Investment in December 2013.

Interview Details – I was connected at our school job fair conference, and got an on-campus interview during their visit. The interview was not difficult, one simple coding problem, one probability problem, and one brain teaser. They invited me on-site to interview at Chicago. Overall I had talked to 3 people (2 technical interviews and 1 just talking). The questions were not hard, but you never know what candidates they are looking for.

Interview Question – Given some coins, how do u flip them to make sure all the coin have the same sides. Some basic knowledge on distributed system.   Answer Question

Financial Technology Associate Interview

Financial Technology Associate
Chicago, IL

I interviewed at Citadel Investment in February 2013.

Interview Details – Two 30 minute rounds on campus and three 1 hour sessions on-site if selected. It starts off with brain teasers and some general conversations. Can get pretty technical (C++ knowledge mostly) in the middle and they may discuss some things in the field of finance and will really appreciate if you show interest in Finance. Most important things going in should be to be comfortable coding in C++ and demonstrating an interest in finance which you should have if you want to work here

Interview Question – Why do you want to work in this financial institution versus working in a pure software company like Microsoft, etc?   View Answer

Financial Technology Associate Interview

Financial Technology Associate
Chicago, IL

The process took 2 weeks - interviewed at Citadel Investment in September 2010.

Interview Details – Initial interviews were behavioral and technical based and I had a following superday in Chicago. The interviews were challenging and were generally questions that tested your ability to reason and understand rather than recite rote memorization.

Work culture seemed very work hard/play hard, tons of very bright people.

Interview Questions

  • Talk about the virtues of a particular trading system, points of failure and possible improvements.   Answer Question
  • Various algorithmic questions, some implementation on whiteboard, eg. fast algorithm for matrix multiplication.   Answer Question

Financial Technology Associate Interview

Financial Technology Associate
Chicago, IL

I applied through college or university and the process took a day - interviewed at Citadel Investment in February 2011.

Interview Details – Got the on-campus interview through the university career service. Two back to back interviews of 30 minutes. One is behavioral and one is technical. Feeling not good about the behavioral one but the guy in the technical one is nice.
The behavioral interviewer seems somehow cold. Questions include: your strong point and weak point? how do you improve your weak point? how much do you know about the company? introduce your achievements to me? Whether you can program? If yes in what language?

The process took 1+ week - interviewed at Citadel Investment in January 2011.

Interview Details – Result is managed by HR and is very obscure how they choose interns....not good.Don't be surprised if you get rejected despite a good interview, had a bitter experience. Work environment is too serious and people seem to work way more than in regular software firms.

Financial Technology associate Program Interview

Financial Technology associate Program
Chicago, IL

I applied through college or university and the process took 2+ weeks - interviewed at Citadel Investment in October 2009.

Interview Details – Citadel recruited for the FTAP program at my University. The first round interview consisted of a 30 minute behavioural and a 30 minute technical with a HR representative and then a FTAP alumni. The technical interview was fairly easy - mostly talked about your background in various fields and probed deeply in topics that the interviewer was interested in.

I was invited to a final round in Chicago. That was three technical interviews of 45 minutes each with a 15 minute behavioural with each interviewer. Similar format as the first round.

Interview Question – Write code to multiply two matrices.   View Answer
