Greeks,Vols,YCurves,Numerical Meth./MC & XVA Guide

This is a practitioner-focused guide that teaches how front-office quants think, compute and defend answers on Greeks, volatility surfaces, numerical methods and XVA. If you want clear, desk-level intuition plus production-ready techniques you can use directly in interviews, desk meetings, or model validation, this module was written for you.

What’s inside

• Greeks made operational — Delta, Gamma, Vega, Theta, Rho: definitions, units, P&L recipes, and hedging rules with worked dollar examples.

• Volatility surface intuition — skew vs smile, sticky-delta/strike behaviours, SABR intuition, SVI notes, and practical surface sanity checks.

• Numerical methods — Monte Carlo variance reduction, control variates, antithetic sampling, pathwise vs likelihood-ratio Greeks, discretization guidance.

• Time-series & volatility dynamics — GARCH intuition, realized vol estimation, regime effects and volatility clustering.

• XVA & exposure — EE profile construction, discrete CVA summation, LGD conventions, and simple approximation recipes for discussion in interviews.

• Interview-ready scripts — “how I’d answer” one-liners and short whiteboard scripts for 25+ common interview questions.

• Worked problems & caselets — 100+ exercises with clear solutions and expected solve-times.

• Production-ready code — vectorised Python snippets (Black–Scholes Greeks, MC with control variates, simple CVA estimator) that you can run and adapt.

• Cheat-sheet & implementation pitfalls — single-page printable reference and a top-10 bug checklist to avoid common mistakes.

Why this guide is different

This is not a textbook summary or a collection of definitions. It is a desk playbook: dense, practical, and designed to convert academic knowledge into fast, defensible desk intuition. Every example ties math to P&L and to how a trader or risk manager actually behaves. That makes it uniquely valuable for interviews and early-career on-the-job learning.

Who this helps

• Quant interview candidates (strats, QR, delta-one, XVA)

• Junior desk quants and risk engineers

• Model validators and quant developers who must explain model behaviour to traders

• Anyone wanting a concise, production-minded reference to Greeks, vol, and XVA
