Ho presentato la mia candidatura tramite l'università. La procedura ha richiesto un giorno. Ho sostenuto un colloquio presso Jane Street (Chicago, IL) nel mese di nov 2016
Colloquio
1 hour earlier phone call. The questions are all about the optimal bid for a bid problem. The interviewer cares more about the intuition about your result instead of the mathematical derivations. 3 more rounds may come around in the next few weeks. I think I have pretty well prepared, but I still got nervous mostly because this is my first time to do phone interview for intern/job.

Assume x dollar(uniformly from(0,1000)) is put into a blackbox. Then you bid on the amount. If x>bid, you get return 1.5x-bid; otherwies you get nothing. The question is what is the optimal bid. Several other different circumstances are also been asked.
Maths probability questions in the first rounds getting harder and harder as you progress. If U have a basic understanding of the matter you should do fine in the first round but you might struggle later on

Colloquio
Was generally okay, went in too nervous and unsure of my answers and so ended up not getting the role. Stopped at the first phone screen. Guy was pretty nice, but wasn't a trader and only worked in HR.
