I applied through university. The process took 1 week. I interviewed at Jane Street (Chicago, IL) in Oct 2014
Interview
I dropped off my resume at a career fair, and get an email a week later to schedule a phone screen. The interview was half an hour, and very quantitative. Lots of statistics and probability questions, a little bit of calculus. No finance stuff at all. I wasn't really prepared for most of the stat stuff
Interview questions [1]
Question 1
There are four coins. For each heads you get, you get $1. You can also re-flip one coin after the initial four flips. What is the maximum you would pay to play this game?

Overall, it was a pleasant interview experience. I answered a few personal questions and encountered one that was slightly confusing, but the interviewer was friendly, and the conversation flowed well overall
Probability questions, nothing crazy but quite open ended, they want to know your thought process and calculations. Pen and paper allowed but no calculator. No OA, a few rounds and got rejected. Zoom call with a trader.
