Have only a phone interview. It was pretty fun and interesting. Interviewer gave hints from time to time but not very often. Questions progressed from easy to more hard but all of them were fun and interesting to think about. Replied in a few days that I didn't make it to the next round.
Interview questions [1]
Question 1
1. What is the expectation of the product of two die rolls?
2. Instead of die imagine drawing cards with the same numbers written on the cards but without replacement, is the expected value of the product smaller/larger/the same comparing to 1?
3. You can split the deck of cards from 2 into two piles. Then you draw a random card form the first and the second piles and compute the product of numbers written on the two cards. How do you split the deck to maximize the expectation of the product?
4. Some other game that involves 10 cakes with 9 being of one flavor, and one being of a different flavor, and the task is to guess correctly as many flavors as you can, but I don't remember the exact rules.
There was a few phone interviews that involved probability and game theory questions. Before a final round interview in hong kong. Interviewers are very nice best to describe your thought process

They asked me probability and gamer theory questions.
Interviewed for two rounds. I passed the first round last year so was able to continue immediately with the second this year. Probability/game theory questions. The interviewers are friendly and helpful.

Question 1
If you roll a dice and receive that amount in dollars but have the option of rerolling up to two times, how much would you like to pay to play this game?
Jane Street’s interview process is fast-paced, multi-round (But if you have a deadline they will react accordingly) , and deeply quantitative: mental math, probability puzzles, game theory..., and conversational talk just before you start doing the problems

Question 1
Some basic probability questions (more like brainteasers) involving expected values and markov chains. You should brush up on the greenbook and be comfortable with n-sided dice and strategies involving dice in general.
