MIT JUST LEAKED THE EXACT DOCUMENT WALL STREET QUANT FIRMS USE TO HIRE PEOPLE. It is called the MIT Quant Bible. And it covers everything the $500,000 a year quants actually know that you do not. Here is what is inside: Probability fundamentals. Conditional probability, Bayes theorem, expected value, variance, joint distributions. The mathematical foundation every trading decision at Jane Street and Citadel is built on. Stats fundamentals. The Law of Large Numbers. Central Limit Theorem. Confidence intervals. The tools quants use to know when a signal is real and when it is noise. Quant research and data science. Least squares, regressions, dimensionality reduction. Real case studies from Two Sigma, QuantCo, and CitiBikes. Quant trading and market making. What market making actually is and how the theory translates into real trading decisions. And then the part that makes this document worth more than most finance degrees. A question bank with real interview questions from Jane Street, Virtu Financial, Optiver, Akuna Capital, Citadel, Hudson River Trading, Two Sigma, Five Rings, and SIG. Not prep questions. The actual questions these firms ask. With answers. The firms charging $50,000 a year for access to this type of preparation are not going to be happy this exists. Bookmark this before it disappears.
