## Describe a Strongly Held View That Proved Wrong Tell me about a technical or product decision you argued for strongly and later learned was wrong. Explain why your original position seemed reasonable, what evidence contradicted it, how you responded, and what changed in the project and in your decision-making afterward. ### Constraints & Assumptions - Choose a consequential disagreement, not a trivial preference or a disguised success story. - Separate facts available at the time from assumptions you made. - Focus on your response after contrary evidence appeared, including any repair or communication you owned. ### Clarifying Questions to Ask - Does the interviewer prefer a technical design decision, a product judgment, or either? - Should the example involve direct disagreement with another person or can evidence alone disprove the view? ```hint Name the falsifying evidence The turning point should be a concrete test, incident, user result, or constraint that made your original model untenable. ``` ### What a Strong Answer Covers - The original decision, assumptions, and reasons it was defensible with the information then available. - The dissenting view or warning signs and how seriously they were considered. - Specific evidence that proved the position wrong and a prompt, accountable response. - Repair of technical impact and trust, plus a durable improvement to future decisions. ### Follow-up Questions - What was the earliest signal you could have noticed? - How did you communicate the reversal to people you had persuaded? - What decision process changed afterward?
