Quant Finance Interview Prep — 1:1 Sessions with a Former Jump Trading Researcher
Quant interviews are unlike any other technical interview: expect probability puzzles, rapid mental math, stochastic calculus, live coding in Python or C++, and brainteasers designed to expose how you think under pressure. The bar is exceptionally high, and generic prep resources rarely match how top firms actually run their processes. The most efficient way to prepare is a direct session with someone who has been through it — from both sides of the table.

What we cover
Probability Puzzles
The classic quant brain-teasers — expected values, conditional probability, combinatorics, and the off-the-wall questions that trip up even strong candidates.
Mental Math & Estimation
Speed arithmetic, Fermi estimation, and back-of-envelope reasoning under time pressure — a skill that separates traders from everyone else.
Stochastic Calculus
Brownian motion, Itô's lemma, SDEs, and option pricing fundamentals — the mathematical backbone of quant researcher interviews.
Coding (Python / C++)
Live coding drills: data structures, algorithms, numerical methods, and HFT-relevant performance questions as firms like Jump and Citadel ask them.
Market Microstructure Basics
Order books, bid-ask spreads, adverse selection, market-making mechanics — foundational knowledge for any trading-desk interview.
Firm-Specific Research
Tailored prep for HFT and prop shops: how Jump, Citadel, Jane Street, Two Sigma, DE Shaw, and similar firms differ in what they test and how they hire.

About Adrien
Former quantitative researcher at Jump Trading — Bayesian optimization for trading strategies, Barra-style risk factor models, and contributions to the Pyth Network liquidity oracle.
MS in Computational Mathematics, Stanford University (ICME). Graduate of École Polytechnique (X), France's top engineering school.
3× International Mathematical Olympiad medalist representing France. Co-author of Les Olympiades de Mathématiques (Bornsztein / Budzinski / Jugé, 2006–2021).
“I know what Jump and similar firms actually test — because I went through it myself, and I've seen what it takes. There's no substitute for working through problems with someone who has been inside.”
