Citadel Financial Technology Associate Intern interview questions

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.
