I applied online. The process took 4 weeks. I interviewed at Jane Street (Hong Kong) in Dec 2019
Interview
I submitted my CV to HK quant intern position then I got an online test a few days after.
3 questions, 30 minites. Pretty basic probability questions, expected value /conditional probability. Then I got a second round phone interview. All about probability again. What was interesting was that I answered the second and third question using the interviewers hint, but I still made it to the third round. Probably because , for the second question I made an educated estimation intuitively . And I gave a correct answer immediately after the interview gave me a hint. I told the interview that I just took probability this semester , so he probably took that into account. I think they care about intuition which can not be taught and the reasoning process. So it is ok to make a mistake or a bit lost at first, don't panic. Now I am preparing for the third round.

Question 1
2 dice. My dice- 20 side 1-20. The other player 30side 1-30. We both flip. If my number is bigger then the other player gave me my number of dollars, vice versa. But if we got the same number , I pay the other player the number of dollars. What is the expected value of my winning or lost ?
A difficult interview. Did not encounter question in Leetcode/my own practise, had to think outside the box to solve it. Interviewer got straight to the point, no behavioral questions, so be prepared.

Question 1
Solve this question, walk me through your thinking.
Some brain teasers and probability problems that are variations of commonly seen quant interview problems. Require smart reacting rather than very high level maths or finance knowledge. Friendly interviewers, active involvement.
The interview process involved multiple rounds, starting with a phone screen covering probability, brain teasers, and market-related questions. This was followed by a technical assessment focused on programming and mathematical problem-solving. The final round included onsite interviews with case studies, logic puzzles, and discussions on trading strategies. The process emphasized clear thinking, structured problem-solving, and strong quantitative skills.
