I applied online. The process took 1 week. I interviewed at Jane Street (London, England) in Jan 2025
Interview
CV check, then online OA. No in-person interview, only a test. Very easy, just requires thorough case checking. There was no behavioural aspect to the online assessment, just technical probability questions.
Interview questions [1]
Question 1
2 questions, both relating to probability. First was a descriptive word-based problem, with around 20 minutes of thinking / typing time, styled like a report. Second was also similar.
