Me postulé a través de una recomendación de un empleado. El proceso tomó 2 meses. Acudí a una entrevista en Jane Street (New York, NY)
Entrevista
First round was a phone call. Lasted roughly an hour, was asked two very high quality math questions. Second was a zoom call, worked with the interviewer on a single problem which was almost a case study.

Problem from first interview: you repeatedly roll a fair 6 sided dice. every roll you add the result to your score. At any time you may end the game and keep your score, however if your total score ever becomes a perfect square you lose with 0 points. How should you play?
Went through 3 rounds of interview, all of which were focused on math. they started with basic questions and built up to harder ones. Also some behavioral questioins at the start of each round
Applied online and passed the resume screen, got invited to a first round, didn't pass, was my first time interviewing for quant and nerves made me answer not quite at the best of my ability
