Context: I'm currently prepping for a Jane Street trader intern interview. They sent me this guide to look over and, while there's not a lot that's new to me or LW, it's got a lot of concepts that are popular here on LW (expected value, conditional probability, priors, adverse selection).
Figured I'd share it here if anyone was curious. I would not endorse it as a good introductory guide, though.
