Jump Trading Quantitative Analyst Interview Questions
& Process

Had a few HR calls before and in between. First round had probability questions, general ML knowledge like lasso, ridge, gradient descent justification, prob inequalities, linear algebra and geometric interpretations of probability. Final onsite included Leetcode problems, stats, harder probability problems, and more in-depth ML knowledge on linear regression basics, PCA, linear algebra, and questions about classes taken. ML knowledge is really important.

I interviewed with Jump Trading. I had three technical interviews: one focused on math and two on coding. I didn't make it past the third interview. The interviewers were nice and helped me solve the problems.

A Jump Trading recruiter reached out about the Power Quantitative Analyst position. I went through two onsite interview rounds, each lasting 3 hours, with a total of 6 interviewers. I didn't get an offer. Some odd things: no job description was provided, and I suspect they were just gathering information, especially since my compensation was never discussed, with the recruiter saying it's 'never an issue.' The interviewers didn't seem to have deep market knowledge, discussing the power market only superficially. Two traders I spoke with didn't give the impression of being strong P&L generators; one mentioned networking as the reason for joining Jump Trading over a hedge fund. Also, their non-compete clause is unusually long and non-negotiable. Ultimately, I was told another candidate had more experience. My advice: don't consider the Power Quantitative Analyst role at Jump Trading London without a clear job description and a discussion about compensation upfront.
