I went with a safe answer about wanting better upfront alignment on requirements, which felt a bit generic the moment it left my mouth.
Choose a project where you made a significant technical decision that, in hindsight, could have been improved. Focus on what you learned and how you would approach it differently now, emphasizing growth and adaptability. Avoid blaming others or external factors; instead, highlight your own decision-making process and the lessons applied to subsequent work.
Pro tip: Select a project where the change would have had a meaningful impact on the outcome, but avoid choosing something that suggests a major flaw in your abilities. Show that you've already applied the lesson to a later project, turning a regret into a strength.
Briefly describe the project, your role, and the goal. Keep it concise to focus on the decision and its consequences.
State clearly what you would change, such as a technical choice, process, or communication approach. Be specific about the alternative you would choose.
Describe the negative outcome of the original decision and how the change would have improved the result, e.g., better performance, reduced technical debt, or faster delivery.
Articulate what you learned from the experience and how it has influenced your subsequent work. Show self-awareness and growth.
Connect the lesson to how you would handle similar situations in the future, especially in the context of the role you're interviewing for.
