I applied online. The process took 1 week. I interviewed at ION Trading (New York, NY) in Mar 2017
Interview
Had a video interview where they gave you a question, one minute to prepare, and one minute to record your answer. Pretty simple behavioral questions. Prepare answers before you go in. Dress professionally.
I applied through university. The process took 3 weeks. I interviewed at ION Trading in Oct 2016
Interview
Starts out with a online interview where you are presented with a sentence and you record yourself answering the questions. You have 4 minutes for each question. You then have an in person interview on campus or a video interview if they don't come to your campus, then a final interview in New York.
