Expected Value Forecasting Interview Questions

Expected value forecasting interview prep for probability estimates, payoff mapping, implied probability, thresholds, and calibration mistakes.

Candidates preparing for prediction, trading, and decision prompts.

Forecast plus payoff

Expected value forecasting combines a probability forecast with a payoff map. Both pieces are needed.

Threshold decisions

A forecast can imply action only after comparing expected payoff with cost, threshold, or alternative choices.

Concrete example

If you forecast a 60 percent chance of a toy event that pays 1 and costs 0.50, the expected net value is 0.6 x 1 - 0.5.

Implied probability comparison

In pricing-style prompts, compare your forecast probability with the implied probability from price or odds.

Calibration check

A forecast that is consistently overconfident will produce poor expected decisions even if the payoff arithmetic is correct.

Common mistakes

Candidates often discuss probability accuracy without mapping the forecast to payoff. Expected value needs both.
