How Quant Interview Question Generator works

How the Quant Interview Question Generator builds reproducible practice sets from a curated bank.

Curation

Every question is hand-written, not LLM-generated. Solutions are checked by a human author. Topics map to the five canonical pillars at first-tier prop firms and hedge funds:

  • Probability — discrete and continuous, expectations, conditional, Brownian.
  • Statistics — estimators, hypothesis testing, multiple testing.
  • Derivatives — Black-Scholes, Greeks, parity, vol surfaces.
  • Microstructure — order books, impact, Kyle's lambda, VPIN, execution.
  • Regression — OLS, BLUE conditions, multicollinearity, regularization, IV.

Difficulty calibration

  • Easy: solvable in 2–5 minutes by a candidate with one course in the topic.
  • Medium: requires a non-trivial step or insight; 5–15 minutes.
  • Hard: non-obvious derivation, multi-step, or unfamiliar setup; 15–25 minutes.

Selection algorithm

Filter the bank by selected topics and difficulty. Apply a Fisher-Yates shuffle seeded with the user-supplied seed (LCG). Slice the first n entries. Same inputs → same set.

Limitations

  • Bank size is bounded — repeated runs with the same filters will eventually exhaust unique combinations.
  • Real interviews include market-making and behavioural rounds we don't cover.
  • Solutions are intentionally terse; consult a textbook for the full derivation.
