Forecast next quarter's query volume and the biggest risk to it
ForecastingHardProblem. Leadership wants a forecast of next quarter's Bing query volume and the single biggest risk to it, to inform planning and investment. How do you build it, and how do you present the risk?
Before you reveal: say your answer out loud, as if you were in the real interview — get your reasoning across clearly first. There is no single correct answer: reading what the interviewer is really after and defending your own thinking is what makes an answer strong.
Strong-answer signal: forecasting as a decomposition with prediction intervals, backtesting the error, and quantifying the top risk as a counterfactual scenario with a contingency and a leading-indicator tripwire. Common trap: giving a single point forecast with no uncertainty, or listing risks qualitatively without sizing the biggest one as a scenario. Trains: forecast-uncertainty; counterfactual-scenario.
