I applied online. I interviewed at Jane Street in Sept 2020
Interview
The process lasts for half an hour and goes on quite smoothly. They first asked me some probabilities problems and brainteasers, and then followed by some coding rounds. The interviewer will give you some hints when you get stucked
Interview questions [1]
Question 1
Give an example of course project which relates to the quantitative trading
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.
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.
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.
