Choose a real, low-stakes technical decision where you had a clear rationale at the time but later saw a better path. Focus on the learning and growth, not the mistake itself, and show how you've applied that lesson since.
Pro tip: Pick a decision where you were missing information or misjudged trade-offs, not one where you were careless—this shows you learn from ambiguity and feedback, which Google values.
Briefly describe the project, your role, and the constraints (time, team, tech stack) that shaped the decision.
State what you chose and why it seemed right at the time, referencing the data or assumptions you had.
Share the actual result, then clearly state what you would do differently now and why that alternative is better.
Summarize the key takeaway—a principle or habit you've adopted to avoid similar pitfalls.
Give a brief example of how you've applied this lesson in a later situation, demonstrating growth.
