   Say this

   Give a real position, state the thesis you held, say what actually happened, and identify the specific analytical error rather than blaming the market. Then the process change it caused.

   Then walk it

   1. State the original thesis in one sentence, exactly as you held it at the time. Reconstructing it charitably in hindsight is obvious and undermines the whole answer.
   2. Then what happened and what you missed. Be specific about the type of error: you overestimated pricing power, you trusted a management forecast, you ignored the balance sheet, you anchored on the purchase price.
   3. Distinguish a bad decision from a bad outcome. Some losses come from good process and bad luck; others from process failure. Showing you can tell them apart is the highest-value part of the answer.
   4. Say what you did when the evidence turned. Did you cut, add, or freeze? Freezing is the honest answer for most people and admitting it is fine if you explain what you now do instead.
   5. Then the process change, concretely. 'I now write the falsifier down when I initiate and check it every quarter' is better than 'I learned to be more careful'.
   6. Avoid stories where you were secretly right and the market was wrong. That is not an answer about being wrong.

   Where candidates lose it

   Choosing a loss you can blame on an external shock. That avoids the question. Pick one where the error was yours and where the lesson changed a specific habit.

   Expect next

   • Was that a bad decision or a bad outcome?
   • What do you do differently now?
   • How long did it take you to change your mind?
