One of the most prestigious and hardest trading interviews, probability, estimation, and live market-making games, judged on how you think.

Prop / Market Maker · Options market maker · Amsterdam

Home of the notorious '80-in-8' mental-math test, raw arithmetic speed is the gate before anyone reads your resume.

Secretive, low OA pass rate, endurance-style superday, probability and EV to near-instant recall for traders, deep C++ for engineers.

Prop / Market Maker · Multi-asset proprietary trading · Chicago

A quantitative challenge from home gates the process; then probability-heavy rounds and a trading simulation across asset classes.

Prop / Market Maker · ETP / ETF market maker · Amsterdam

A timed mental-math and sequences test with negative marking, then ETF/ETP arbitrage reasoning under deliberate interviewer pressure.

Prop / Market Maker · Options market maker · Chicago

Two online assessments (timed math + coding) route you toward the quant or discretionary track; then options intuition and trading games.

Buy-side · Multi-strategy hedge fund · Miami, FL

Among the hardest quant interviews, open-ended probability where you must state assumptions, plus clean Python under a timer.

Buy-side · Quantitative multi-strategy hedge fund · New York City

Academic, research-driven, and extremely selective, open-ended brainteasers with 'no single right answer' and deep project deep-dives.

Buy-side · Multi-strategy pod-based hedge fund · New York City

Pod-based, so interviewers (individual PMs) can ask almost anything, prepare a two-pronged screen of probability/stats and pandas/coding.

Buy-side · Systematic arm of a multi-strategy fund · Stamford, CT

Dialogue-driven interviews where 'I don't know' is acceptable, statistics, time-series, and a deep-dive on your own research.

Research-communication-heavy, two homeworks (coding + data science) and a discussion of alpha sources across asset classes.

Buy-side · Systematic / quant hedge fund (tech-driven) · London

An applied-ML take-home project is the main filter, clean, well-reasoned analysis matters more than exotic models.
