I applied online. The process took 1 week. I interviewed at Jane Street in Oct 2015
Interview
I submitted a resume through Jane Street's website. A couple days later they responded to schedule a phone interview. We scheduled the phone interview for the following Thursday. A trader called me from the trading floor and we went through four math questions. The entire interview took around 25 minutes. I wasn't able to answer the final question, so I don't expect a second round.
Interview questions [1]
Question 1
The only difficult question I was asked went as follows:
"You and your opponent flip a coin. If the first player gets heads, the second player pays him $30. If he flips tails, the coin goes to the second player. If the second player flips heads, he wins $30 from the first player. How much should you pay to go first?"
The interviewer was very informative. The questions appeared basic initially, but they required deeper reasoning, strong fundamental knowledge, and careful problem-solving instead of simple, straightforward answers throughout the interview process.
The process was structured and intellectually challenging. It typically involves an initial recruiter screen, followed by probability, mental math, expected value, and game-style problem-solving interviews. Interviewers focus more on reasoning, communication, and adapting to feedback than memorized answers.

Question 1
You have two opaque boxes in front of you. At each turn, you may choose one of two actions:
Place: put one coin into one of the two boxes, chosen uniformly at random.
Take: choose one of the two boxes uniformly at random, take all the coins inside, and empty that box.
You play for exactly 100 turns. Your goal is to maximize the expected number of coins you collect.
What is your optimal strategy?
Several phone calls to go to the final round. The phone calls consists of mathematical, probabilistic brain teasers which was not that hard for a mathematics major. Final round was to harsh for me, strong mentality is required
