Firm-tagged practice collection

Quant practice questions tagged Jane Street.

This independent collection groups reviewed Quantenius records carrying Jane Street attribution metadata and no more than eight firm labels. The current set is broad, with substantial coverage of combinations and permutations, conditional probability, expected value, game strategy, dice, and coin reasoning. That mix is useful for alternating between quick structural observations and explicit calculations: determine whether order matters, condition on the correct evidence, define a payoff before averaging it, and justify an optimal response rather than guessing. The metadata is historical study organization, not a representation of the firm's current interview process. Questions may have appeared in multiple preparation sources and can carry more than one firm label.
