Quant Finance is known for having a highly unique interview process compared to other areas in finance. There is a strong emphasis on your ability to guide the interviewer through your solution by thinking out loud and seeking hints or clarifications during the process.

These interviews do not require specific knowledge of probability questions involving Markov chains, martingales, or similar concepts. However, more often than not, an understanding of these topics will help you tackle the questions effectively. You can find more details at this link.

CoachQuant's Quant Finance Phone Interview is considered the easiest stage. During this interview, you'll be asked a variety of brain teasers, which may include mental math problems, dice rolls, card games, or coin-related probability questions. Typically, the examiner will propose a variation of the initial problem and ask you to consider the scenario under different conditions. More often than not, these variations don't have a closed-form solution, and the examiner is interested in observing how you arrive at a rational decision.

CoachQuant mock interviews are designed to simulate the real-time pressure of a quant finance interview. They help you practice thinking out loud while working toward an answer and encourage you to ask smart questions to clarify the problem, ultimately preparing you to excel in your finance interview.
