J'ai postulé en ligne. Le processus a pris 3 semaines. J'ai passé un entretien chez Jane Street en sept. 2025
Entretien
1 Zoom interview. Followed by an on-site superday 2+1 interviews: 2 in the morning, 1 final interview in the afternoon if you passed the morning interviews.
Format is the same as described on the official website and their sample interview video on YouTube. The problems are practical coding (not LeetCode) with follow-ups, and the interviewers are nice and helpful.
We jump into the technical interview immediately at the start of the interview, followed by follow-up questions if there's time left. I have encountered algorithm implementation (with algorithm explanation given) and API implementation type problems.

Fast and efficient, everyone is friendly.
The interview was fully techinical, no background or behavioral questions for me. The style is very collaborative — asking for hint in a proper way would be considered a plus I guess.

First round was online, one round of 1hr class design questions.
Given a class interface, you need to implement it with another given class interface. My question is like a general tree question.
You kinda need to go far enough to get to next round, so if you're too slow or have trouble solving easier parts, you cannot make it. I didn't move on.
