Jane Street Software Engineer interview: final onsite mattered most

Jane Street·Software Engineer·Reported Jul 2026

I started with a virtual round and then moved to an onsite. The questions blended coding with system-design-style work, but they emphasized real-world systems more than academic exercises. By the onsite, it was clear that this was the most important stage and that the bar was highest there.

I did not perform well enough in that final stage to move forward. The process was intense, and my main takeaway was simple: the final interview mattered much more than the earlier steps, and my performance did not match what they wanted.

Location: London, England. Overall feedback: neutral. Offer status: no offer.
