First-hand accounts from people who interviewed at Jane Street.
Product Intern
I did an OA, then a first round, then went to the final round 1. I heard there were 4 final rounds in total. The questions I got were similar to what other people posted on Glassdoor, so good on you if you're reading this. The only thing I'm not happy about is that they don't give out feedback even though I reached the final round.
- Can you design a car replacement program for a car rental company?
Product Intern
The online assessment (OA) for the 2026 cohort had 10 questions. These questions covered topics ranging from order books to probability and data. The focus was more on logical thinking and basic probability principles rather than specialized trading terminology.
- After a sequence of orders, what is the state of the order book?
- Describe the structure of an order book given a set of executed orders.
- What would an order book look like following a specific sequence of transactions?
Product Intern
After applying, I took an online exam that lasted about an hour and was entirely multiple choice. They gave me study material about the order book beforehand. The next round was an online interview, which was unexpected. I was given a problem and allowed to brainstorm and think through it with the interviewer for about 45 minutes on Zoom, including introductions and their questions. The interviewer was very patient and listened well, even when I was thinking out loud and got a bit lost. It was a fun experience, and I enjoyed discussing a random topic and brainstorming. I haven't heard back yet.
- When should a company make an investment in their service for a particular business?
- What factors would you consider to justify the decision to invest?
- What parameters would you use to evaluate whether it was a good move or not?
