🔥 What’s Inside the 200 Problems?
This is not a simple list of Q&A.
Each problem is formulated using actual interview themes, followed by complete, step-by-step derivations, intuition building, and memory anchors.
1. Probability Theory & Combinatorics (Tier-1 Must-Knows)
Monty Hall with asymmetric revelation, matching problems, derangements, hypergeometric inference, Poisson limits, negative binomial transitions, random permutations, occupancy models, inclusion–exclusion.
2. Stochastic Processes & Markov Chains
Poisson processes, arrival races, conditional arrival times, Markov chain convergence, spectral gap intuition, multi-state transitions, pattern-matching stopping times (HTH vs HHH), Gambler’s Ruin with asymmetry.
3. Advanced Statistics & Inference
Likelihood ratio tests, Bayesian updating, Beta posterior intuition, Benjamini-Hochberg FDR control, confidence interval reasoning, bootstrap variance behaviour, KS-test limiting distribution.
4. Quantitative Finance & Pricing
• Duration–convexity approximation
• MSR valuation sensitivity
• TIPS breakeven, inflation swap pricing
• Credit spread → hazard rate relationship (credit triangle)
• LIBOR → SOFR transition valuation impact
• Mortgage prepayment modelling (CPR effects)
• Swap, futures and SOFR expectations
• Compound Poisson P&L modelling through PGFs
5. Brain Teasers Used by Prop Trading Firms
Ball-difference puzzles, structured counting, randomness paradoxes, Russian roulette adjacency, coupon collector with a joker, expected stopping positions in shuffled decks.

✔ Full Mathematical Derivations
Every equation is derived, explained, simplified, and supported with proportional relationships.
✔ Memory Anchors
Each question ends with a short formula or relationship to help you internalize concepts quickly.
✔ Quant-Friendly Format
Clean notation, intuitive structure, and direct application to real interviews.
✔ Builds Both Intuition & Speed
You learn not just what the answer is, but why it works — crucial for interviews where follow-up questions are aggressive.
✔ Designed to replicate Goldman/JP Morgan/Morgan Stanley interview style
Many problems reflect real patterns asked by actual desks (rates, FX, credit, equities, risk, prop trading firms).
