## Question Describe a difficult technical decision you made. Present the competing options, constraints, evidence, people involved, decision rule, and outcome. Explain what would have caused you to choose differently. ### Constraints & Assumptions - Choose a decision with real uncertainty and consequences. - Include at least one rejected option that a strong engineer could reasonably prefer. - Distinguish reversible from irreversible aspects. - Do not judge the decision only by whether the eventual outcome was good. ### Clarifying Questions to Ask - Would you like an architecture, reliability, data, or build-versus-buy decision? - How much technical detail should I include before the decision process? ```hint Explain the threshold A decision is easier to evaluate when you name the evidence or future condition that would flip it. ``` ### What a Strong Answer Covers - Context and explicit decision criteria. - Alternatives, risks, and uncertainty. - Evidence collection and stakeholder involvement. - A reversible rollout or mitigation for the chosen risk. - Outcome, learning, and a credible flip condition. ### Follow-up Questions 1. Who disagreed most strongly? 2. Which assumption had the weakest evidence? 3. How did you avoid outcome bias afterward? 4. What would you decide today?
