Applied online. Received email for online programming test on Heckerrank soon. A few weeks later scheduled a web conference for final interview. I did a terrible job in the final interview so a rejection arrived the next morning. However, the questions are not hard at all if you are familiar with probability and statistic staff. They did not ask any financial questions, and as the interviewer said, they are willing to teach you finance. All you need is good mathematical knowledge and good programming skill.
