Question set

  1. Q1 · derivatives · medium

    Why is the Black-Scholes price of an at-the-money call approximately 0.4 · S · σ · √T?

  2. Q2 · stats · medium

    You estimate Sharpe = 1.0 over 252 days. Construct an approximate 95% CI on the annualized Sharpe.

  3. Q3 · microstructure · medium

    What is adverse selection in an order book?

  4. Q4 · probability · medium

    100 people board a plane in order; the first sits randomly, others in their assigned seat if free, else random. P(last person gets their assigned seat)?

  5. Q5 · probability · medium

    X and Y are i.i.d. uniform on [0,1]. What is P(|X − Y| < 0.1)?

  6. Q6 · stats · medium

    Why does multiple-testing inflate the false-discovery rate, and what's one classic correction?

  7. Q7 · stats · medium

    What is the bias-variance decomposition of MSE?

  8. Q8 · regression · medium

    Why are robust (HAC / Newey-West) standard errors used in financial regressions?

How to use

Step-by-step

Full calculator guide →
  1. 1

    Pick category (probability, brain-teaser, time-series, programming, behavioral) and difficulty (junior/mid/senior).

  2. 2

    Generate 5-10 questions. Solve each without aids; the timer (optional) replicates interview pressure.

  3. 3

    Reveal the model solution after solving. Read the alternative approaches when listed — interviews often test which approach you pick, not just whether you solve.

  4. 4

    Track which questions you've answered. The generator avoids near-duplicates on subsequent sessions.

  5. 5

    Use the 6-week prep cycle on the methodology page: weeks 1-2 fundamentals, 3-4 mid-difficulty, 5-6 senior + behavioral.

FAQ

What categories does the generator cover?

Five from the methodology page: probability and combinatorics, brain-teasers and stochastic processes, time-series statistics, programming (algorithmic + finance-flavored), and behavioral. Each category has difficulty tiers calibrated to junior/mid/senior interviews at quant-shop tiers (Tier 1: Jane Street, Tier 2: Bridgewater, Tier 3: typical hedge fund).

Are these real interview questions?

Most are derived from public collections (Quant Job Interview Questions and Answers, Practical Guide to Quantitative Finance Interviews) plus user-contributed variations. Direct copies of post-2020 actual interview questions are excluded by the methodology page — interviewers rotate questions and we don't want to give specific shops' active questions away.

How do I use this to prep?

Pick a category, set difficulty, generate 5-10 questions per session. Solve without aids first, then check the model solution. The tool tracks which questions you've answered and biases away from repeats. The methodology page recommends a 6-week prep cycle: weeks 1-2 fundamentals, weeks 3-4 mid-difficulty, weeks 5-6 senior + behavioral.

What's the difficulty calibration?

Junior: standard probability and basic regression — should be solvable in 5-10 min. Mid: requires applying multiple concepts together, stochastic process derivations — 15-25 min. Senior: open-ended, multiple valid approaches, requires articulating tradeoffs — 30+ min. The labels are calibrated to interview transcripts in the methodology dataset.

Does it grade my answers?

It provides a model answer with full derivation. For the open-ended senior questions, model answers show one good approach plus 1-2 alternatives. The grading is self-assessment — there's no auto-grader for free-form quant answers.
