J'ai postulé via un recruteur. Le processus a pris 1 semaine. J'ai passé un entretien chez Jane Street en mars 2017
Entretien
I was contacted by a recruiter, and we set up a phone interview with a developer at Jane St. I solved the question, but had a lot of help, so I received a rejection in two business days.
Questions d'entretien [1]
Question 1
Given a matrix of chars from the set {"u", "l", "d", "r", "x"}, where the matrix is guaranteed to have one "x," and each of the other chars represent a direction up, down, left, and right, and a point on the matrix, write a function that returns true if "x" can be reached by following the specified path.
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.

Entretien
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.

Entretien
My experience interviewing at Jane Street was definitely challenging, but also surprisingly collaborative. Instead of focusing only on whether I could get the right answer quickly, the interviewers were much more interested in how I approached problems and explained my thinking. I worked through a few coding questions involving data structures and algorithms, and there were also some probability-style questions that tested logical reasoning. The interviewers were clearly very sharp, but they were also approachable and encouraged me to talk through my thought process the entire time. When I got stuck, they would sometimes guide me with small hints so we could keep exploring the problem together. Overall, it felt less like a typical high-pressure interview and more like a thoughtful technical conversation with experienced engineers.
