Chicago Venture Partners Algorithmic Trade Developer interview questions

Overall the interview process was alright, though as it went on I realized that I was less and less of a fit for the role. There was mainly one interviewer, who asked me questions about the kind of programming I had done. That was fine, just not what I wanted to talk about. He also asked some questions concerning linear algebra, one of the math classes I have taken but not for a long time, so it felt a little unfair that he was mainly drilling me on one class of math I took almost 3 years ago.
