I applied online. I interviewed at Jane Street (Chicago, IL) in Feb 2016
Interview
I applied online. They responded offering me a phone interview in about one weeks time later. I had one 30 minute phone interview which I totally bombed. Overall the process went completely smoothly although the interview was difficult to figure out on the fly.
Interview questions [1]
Question 1
How many ways are there to shuffle a deck of card. Followed up by a few other way more difficult questions.
The process began with serveral online tests for maths and logic. They gave a personal interview to get to know the candidate better and evaluate fit for the company/role, then held a technical interview covering maths and logic problems.
We started with a bit of small talk, followed by some probability questions. Ended with some basic algebra questions, Make sure to ask questions if you have any. Good experience, feels like the interviewer was trading.

I interviewed at Jane Street (Hong Kong)
Interview
Fun and filled with unexpected questions. The questions rely on fast thinking and fast calculations, and sometimes intuition because there is no sufficient time for me to work through the whole problem.
