Pick something real but not career-ending to talk about.
Choose a disagreement that was about technical direction or prioritization, not personal conflict, and show that you sought to understand your manager's perspective first. Then describe how you presented data or alternatives, and emphasize that you ultimately supported the final decision even if it differed from your view.
Pro tip: Frame the disagreement as a shared problem-solving exercise, not a battle of wills—managers want to see you can push back respectfully and then commit fully to the team's decision.
Briefly describe the project, your role, and the specific decision where you and your manager disagreed. Keep it concise and focused on the technical or business issue.
State your viewpoint clearly and back it with data, user impact, or engineering trade-offs. Show that your disagreement was reasoned, not emotional.
Explain how you raised the issue privately, listened to your manager's rationale, and sought to find common ground or a compromise.
