I applied through university. I interviewed at Jane Street (London, England) in Sept 2016
Interview
It is just an open house where interested jib applicants ask questions. Very good overall. Five or six current employees introduce their own jobs and show us around. The open house ends with pizza and free conversation with those employees. It takes 4 hours in total.
Interview questions [1]
Question 1
They basically answer questions and encourage prople to apply. The London office is expanding.
