I applied online. The process took 1 day. I interviewed at Jane Street
Interview
First interview about mental math and probability questions and it was a phone interview. Make sure your connection is good. I had some trouble with my cell phone. Questions were pretty easy and interviewer was willing to help in case you got stuck. You were not supposed to use pencil and paper. All calculations need to be done in your head. Easy questions for the first round but you need to think and answer fast. At the end of the interview they ask to give a confidence interval of your answers.
I got rejected after the second round phone interview which was more difficult than the first one.
I interviewed at Jane Street (London, England) in Jan 2026
Interview
einen runden spiele am Vormittag und dann programmieren am nachmittag.
Biem spiele hat man parallel wetten sollen, also ein buy and sell zwishudn ein sechseiiger Würfel und sowas. oder karten wetten auf das die karte rot ist und zwischen 5-9 was zahlst du für diesen output und so. anrfang rechnen danach abschärtzen udn Ergebnisse interpretieren
Overall, it was a pleasant interview experience. I answered a few personal questions and encountered one that was slightly confusing, but the interviewer was friendly, and the conversation flowed well overall
Probability questions, nothing crazy but quite open ended, they want to know your thought process and calculations. Pen and paper allowed but no calculator. No OA, a few rounds and got rejected. Zoom call with a trader.
