J'ai postulé en ligne. Le processus a pris 1 jour. J'ai passé un entretien chez Jane Street en déc. 2018
Entretien
Applied online and they scheduled a phone interview. Skype and an online editor were used for communication.
The interviewer was very focused on the code that I was writing. He asked detailed questions about every design decision I made, from choosing a data structure to structuring an if statement. The code wasn't long but it was complicated.
Questions d'entretien [1]
Question 1
Can't say the tasks but will explain some key points.
There was only one question wih two parts.
First part is a standard software engineering question where you implement a simple function using the structures from the language library and argument why it is fast and easily maintainable.
The second part is harder. The function from the first part is used in a more complex algorithm where you need to supply a couple of other functions. The focus is on speed and you will probably need a custom data structure.

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.
