I applied through a recruiter. The process took 1 week. I interviewed at Jane Street in Oct 2015
Interview
Email, phone interview
Got an email from HR recruiting after submitting my resume at a career fair.
Had a phone screen, wasn't super hard but I was super nervous (1st internship interview) and the interviewers were super nice and helped me even though I was clearly nervous
Asked a few brain teasers such as what's the minimum number of people to put in a room to make sure at least 6 have the same birthday month.
the only thing is that it was all mental math so I would definitely prepare for that. At least for me, mental math is my mega Achilles heel and some of the questions can trip you up if you have trouble keeping track of things in your mind
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.
