I applied through an employee referral. I interviewed at Jane Street (Hong Kong)
Interview
1 stage was a call from someone at Jane Street just for screening purposes to ask me about my motivations. Was then flown out to HongKong for an in-person interview, met with 3 people there and did technical interview. Heard back on the last day before I left Hong Kong
Interview questions [1]
Question 1
Some of the questions were:
- How much wood could a woodchuck wood if a woodchuck could chuck wood? (brain teaser)
- How many carrots are made each in year in Nepal? (basic market sizing question)
- What's 568,582 x 38,1731 (Basic Mental Math Question) and then they followed up with "now divided what you got by 64.31" they give you 30 seconds to answer
- What was Robert Granieri's childhood dogs name? (testing knowledge of the company)
I applied online. I interviewed at Jane Street (London, England) in Oct 2024
Interview
Interview process at Jane Street typically includes an initial recruiter call, followed by multiple technical interviews focused on probability, statistics, mental math, game theory, and market intuition. Later rounds involve trading simulations, behavioral fit, and a final onsite assessing decision-making under uncertainty
