Probability
Probability is the foundation of most quantitative interviews. This section teaches how to model uncertainty, condition on information, reason using symmetry, and recognize common probability structures.
7 lessons
Combinatorics
Quant interviews often disguise counting problems as probability questions. The key skill is recognizing what is being counted and whether order matters.
8 lessons
Expected Value
Expected-value problems are central to quant interviews because they test modeling and decomposition rather than arithmetic.
8 lessons
Statistics
Statistics questions test whether you can summarize data, estimate parameters, and avoid fooling yourself with noise — the daily work of a quant researcher.
8 lessons
Distributions
A small set of distributions appears again and again. Knowing their parameters, moments and defining properties lets you recognize them instantly.
6 lessons
Stochastic Processes
Stochastic processes model how randomness evolves through time: random walks, Markov chains, Poisson arrivals and Brownian motion.
8 lessons
Linear Algebra & Optimization
Linear algebra and optimization underpin portfolio construction, factor models and machine learning.
10 lessons
Derivatives & Finance
Pricing by no-arbitrage, the Greeks, fixed-income sensitivities and portfolio risk — the finance vocabulary interviewers expect you to use fluently.
10 lessons
Market Making & Trading
How quotes, spreads, information and inventory interact, and how to size and evaluate bets.
8 lessons
Algorithms & Quant Development
The algorithmic toolkit behind quant-developer interviews: complexity, core data structures, search, sorting, dynamic programming and randomized algorithms.
