I applied online. I interviewed at Jane Street (New York, NY) in Sept 2025
Interview
Initial case study using excel + a write-up. 1 math/stats question where they dig into your thought process. They kept asking why, what your intuition was. Seemed like actual answer didnt matter as much as having a clear thought process. Followed by 2-3 simple behaviorals. Interviewer was friendly and the whole process was streamlined.
There are three rounds total: the first two are zooms with a mix of numerical problems and behaviorals (second round focuses a little more on your background); final round is in person at the nyc office.
Take home assessment followed by basic problem solving interview. Simple maths questions like how long to go round a race track at different speeds, angle between two clock hands. .
