The process took 1+ week. I interviewed at Jane Street (Montreal, QC) in Oct 2017
Interview
Got invited for the first round- phone interview. Questions are not hard but I am too nervous so I did not get the second round unsurprisingly. Do not think too much about probability. I am expert in probability but unfortunately none is related to hard prob Q. They reply emails very soon and very nice.

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.
