Probability, expected value, fast arithmetic, and the betting and market making games trading firms run in every round. Learn the patterns once and the questions stop feeling like tricks.

1What trader, researcher, and developer interviews testTrading firms hire three kinds of people and interview each differently. Know which seat you want before the first phone screen, because the questions follow from it.6 min
2Probability and countingProWhen outcomes are equally likely, probability is a count: favorable outcomes over total outcomes. Most phone screen questions are a counting problem in disguise.9 min
3Conditional probability and BayesProNew information shrinks the set of possible outcomes. Conditioning is recounting inside that smaller set, and Bayes is the same idea run backwards.10 min
4Expected value and fair pricesProExpected value is the average outcome over many plays. It is what a game is worth to someone who will play it many times, and it is the first number a trader wants.9 min
5Mental math under a clockProFast arithmetic is a set of habits: split numbers into easy pieces, round and correct, and know the common fractions cold.7 min

6Brainteaser patterns, worked step by stepProMost quant brainteasers fall to one of a few moves: set up states and solve the equations, use linearity of expectation, or find a symmetry or a fair game.11 min
7Market making games and the bid and askProA market maker quotes a price to buy and a price to sell and earns the gap. The interview version is a game where you quote on something uncertain and the interviewer trades against you.10 min
8Edge and position sizingProEdge is how much a bet makes on average. Sizing is how much of your bankroll to put on it. A good bet sized badly still goes broke.10 min
9Options basics for tradersProAn option pays only on one side of a strike. Pricing one on a die is the same expected value math you already know, and it shows why volatility makes options worth more.10 min
