Me postulé en línea. Acudí a una entrevista en Jane Street
Entrevista
Applying for winter internship. Had one interview thus far over phone, spoke with Tim who was nice and patient when I took a while to answer a question. Was somewhat friendly but mainly was professional and to the point. Interview questions were mental math and logic, received a second interview for later.

Overall, it was a pleasant interview experience. I answered a few personal questions and encountered one that was slightly confusing, but the interviewer was friendly, and the conversation flowed well overall
Probability questions, nothing crazy but quite open ended, they want to know your thought process and calculations. Pen and paper allowed but no calculator. No OA, a few rounds and got rejected. Zoom call with a trader.
