Expected Value Interview Final Checklist
Expected value interview final checklist for outcomes, probabilities, payoff signs, costs, risk assumptions, and communication.
Candidates in final review mode for EV, fair games, and decision questions.
Outcome checklist
List every possible payoff state. If outcomes are grouped, make sure the groups cover all cases without overlap.
Probability checklist
Check whether probabilities are unconditional or conditional on reaching a branch. They should sum correctly within the relevant space.
Payoff checklist
Use net payoffs with correct signs. Subtract entry costs, fees, penalties, or spreads when the prompt includes them.
Risk checklist
Ask whether the prompt wants fair value under risk neutrality or an actual decision under risk and constraints.
Explanation checklist
State the model, compute the expectation, sanity-check the result, and explain what would change under different assumptions.
Common mistakes
Candidates often produce a number without the setup. In EV interviews, the setup is usually what the interviewer is testing.
