I applied through college or university. The process took 3 weeks. I interviewed at PEAK6 (Chicago, IL) in Nov 2016
Interview
Applied on campus portal and their website. A few days after did an online reasoning test, then interview two weeks from then. The interview was with 2 different interviewers. Started off right away with math questions and some probability questions. Then it ended with more behavioral questions especially with the second interviewer.
