I applied online. The process took 2 weeks. I interviewed at Jane Street in Aug 2016
Interview
Applied online to Jane Street Hong Kong and got an email a few days later asking to set up a phone interview.
The actual interview was quite casual, started off with around 1min of discussing what the internship would entail and then moved onto probability and logic questions.
Whole interview took around 20min.

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.
