Choose a bounded example
A question about handling disagreement does not require your entire career story. Pick one situation and explain the goal, constraints, disagreement, and your responsibility.
Spend the time on your actions
Instead of saying you communicated proactively, explain whom you consulted, which facts you checked, what options you proposed, and how the decision was made. Separate your contribution from the team's shared result.
Include the outcome and reflection
Use reliable metrics when you have them and explain their scope. Otherwise describe an observable change without inventing a percentage. Say what you would repeat or change next time; this provides useful detail for follow-up questions.
Review instead of memorizing
After practice, read the transcript and find vague statements. Add one concrete fact to each, answer again, and check whether background information has crowded out your actions.
