I applied through college or university. The process took 1 week. I interviewed at Jane Street in Feb 2017

All probability questions, basically no behavioral questions at all. This was a first round interview, so the questions were easy. I was just very nervous so I had a hard time but if you keep a cool head the first round shouldn't be hard.
