Volatility Quant Interview Guide
Volatility quant interview guide covering realized volatility, implied volatility, surfaces, skew, hedging, forecasting, and options risk.
Candidates preparing for options, derivatives, risk, and systematic trading interviews.
Volatility measures uncertainty, not direction
Volatility describes the magnitude of price movement over a horizon. It is central to options pricing, risk, sizing, and execution decisions.
Realized and implied volatility differ
Realized volatility is computed from historical returns, while implied volatility is backed out from option prices and market expectations.
Concrete example
An interviewer may ask why implied volatility is above recent realized volatility before earnings, where event risk and risk premium matter.
Surfaces add strike and expiry dimensions
Options markets quote volatility across strikes and maturities, so skew, smile, term structure, and surface movement are part of the answer.
Common mistakes
Candidates often treat volatility as one number. Strong answers specify horizon, estimator, sampling, option expiry, and market context.
