Jane Street online assessment
Built by Jane Street
- Format
- Jane Street's own description is short: multiple choice and short answer questions. They also say their interviews are designed to need no preparation, which is a statement of intent rather than a reason to sit it cold.
- Timing
- About an hour, per Jane Street's careers site. They publish no question count, no marking scheme and no pass mark.
- What is uncertain
- Candidate reports add specifics: HackerRank hosting, roughly ten questions across four modules, heavy probability and expected value. Jane Street confirms none of it, so it is on this page as hearsay and nothing more.
- How to practise
- Practice Questions for the probability and brainteaser end, Dice Markets for expected value under uncertainty.
