I applied online. I interviewed at Jane Street in Nov 2022
Interview
Zoom (audio only) coding interview. It wasn't difficult overall. I was a bit confused with what they were asking me to implement at first but after asking some questions it became clear. The rest of the interview went smooth,

Question 1
Was asked to implement some functions that operated on a stack and altered its content according to a set of rules defined at the beginning of the interview.
I applied online. I interviewed at Jane Street (London, England) in May 2014
Interview
3 phone calls, then on-site interviews (also three). Questions vary: some algorithm questions, also design questions and questions involving functional programming (I would tell it is not such important to know OCaml, but concepts of functional programming [monads, types, tail recursion] - I would tell that it was not "basic" functional programming, but these more difficult concepts). Everyone is professional, it was easy to understand what they are asking and you can ask questions to get clarifications.

Question 1
Two of the interviews had algorithm questions, other two had design questions, one functional programming interview and one coding interview.
They came to our university and gave a talk, so I send them my resume and attended a phone interview days later, the guy who interviewed me was very nice and I kind of felt that he was the smartest person who ever interviewed me. it was a pleasant experience, but sadly I got rejected soon after the interview, lol.

Question 1
There is only on question, design the interface of a functional immutable queue, better in a functional programming language.
