Tell me about a project where you raised the quality bar beyond the original plan. What risk or weakness did you identify, how did you persuade others it mattered, what specific mechanism changed, and what evidence showed that quality improved? ### Constraints & Assumptions - Choose an example where quality had an observable technical or customer consequence. - Do not equate quality with adding every possible feature or delaying indefinitely. - Explain how the improvement fit the delivery constraints. ### Clarifying Questions to Ask - Which dimension of quality was weak: correctness, reliability, security, usability, or maintainability? - What baseline or failure evidence was available? - Who could approve the added work or changed acceptance criteria? ### What a Strong Answer Covers - A specific gap connected to user or operational risk. - A proportionate intervention such as an invariant test, staged rollout, SLO, review gate, or design simplification. - Influence based on evidence and tradeoffs rather than an appeal to perfection. - A before-and-after signal and proof the control caught or prevented relevant failures. - A durable standard that did not create unnecessary process burden. ### Follow-up Questions - What did you explicitly leave out to protect the schedule? - How did you know the new control was testing the real risk? - Did the quality mechanism continue after you left the project?
