Breakdown of the interview: 00:01 Interviewer asks the first question: Say you have $100 and are betting on a fair coin flip. Before you flip the coin, you make a bet B, that can be up to the amount of money you have. If you win, you win 2 times as much as your bet (and get your original bet back). But if you lose, you lose your bet. You’re going to be tossing this coin 100 times. What is the optimal bet size at each flip to maximize long-run expected winnings? 00:29 The candidate starts by asking clarifying questions. 0:43 The candidate, right off the bat based on his intuition, answers the first part of the question. 2:12 An instructor highlights how the candidate quickly comes to an initial conclusion — this is a good signal in an interview. 2:33 The interviewer clarifies the candidate’s response and asks “What’s the optimal bet size?” 4:56 An instructor breaks down the candidate’s solution, and whiteboards the theory. 6:13 The interviewer asks a follow up question: “what if instead of starting with $100, we start with $150?” 9:40 An instructor whiteboards and explains the candidates answer to “calculate the expected winnings of playing this game”. 11:16 The interviewer asks a new question: You keep rolling a fair dice until you roll 3, 4, 5 — in that order consecutively on 3 rolls. What is the probability that you roll the die an odd number of times? 11:31 The candidate starts answering this question! 18:31 An instructor explains how to dissect this question, and whiteboards the intuition behind calculating the probability that odd or even wins. This question comes down to creating a system of questions, and the instructor explains how to create these equations. Quant finance careers on average pay over $500K.
