I applied online. The process took 5 weeks. I interviewed at Jane Street (London, England) in May 2019
Interview
After having succeeded solving their online challenge and phone interviews, I went to London onsite and had two interviews in the morning, of one hour each, followed by a lunch with more junior employees.
Interview questions [1]
Question 1
Questions where algorithmic exercises. To make the interview process more fair, it is better to not divulgate them.
The process started with an initial virtual round, followed by an onsite interview. It included a mix of system design and coding problems focused on real-world system applications. Unfortunately, I didn’t perform well in the onsite, which was the most critical stage.
It was a very quick and painless process. Recruiter very responsive, kind interviewers. High implementation and difficult problems, so failed onsite after 3 interviews and a Question and Answer Session.
Did not pass the initial coding round. I tried to explain my thought in details to the interviewer but failed to translate my thought into code. So far interviewer is very nice.
