I applied through college or university. I interviewed at TradeStation (Boston, MA)
Interview
Company came to our university campus. They selected a group of students from our program and then we had 30 minute interviews 1:1 with a hiring manager. There were two hiring managers, both of them asking more or less the same type of questions.

Round 1: mostly behavioral questions. They wanted to know my interest in coding and whether I was willing to learn new languages and apply them to stochastic control problems.
