Suggested Approach

Choose a real, low-to-medium-stakes technical disagreement where you genuinely listened to the other person's perspective before advocating for your own. Use the STAR method to show how you separated the problem from the person, sought data or a small experiment to resolve the impasse, and explicitly describe the repaired or strengthened relationship afterward.

Pro tip: Anthropic values intellectual honesty and collaborative truth-seeking, so frame the disagreement as a shared search for the best answer rather than a contest you won. If you ultimately changed your mind, say so—it signals you optimize for outcomes, not ego.

1. Set the scene briefly

Name the project, the other person's role, and the decision at stake in one or two sentences. Keep context tight so most of your answer focuses on how you handled the conflict.

2. Explain the disagreement without villainizing

State both positions fairly and why each was reasonable. Show you understood their constraints, incentives, or technical concerns before pushing back.

3. Describe your resolution process

Explain how you de-escalated, sought data or a small experiment, and proposed a path forward. Highlight listening, curiosity, and a bias toward evidence over opinion.

4. Share the outcome and relationship

State what was decided, what you learned, and how the relationship evolved. Be specific about trust, future collaboration, or process improvements.

5. Reflect on what you'd do differently

End with one honest lesson about communication or judgment. This shows self-awareness and growth rather than a rehearsed victory story.

Key Points to Mention

  • Active listening and restating the other person's position before responding
  • Separating the technical problem from personal dynamics and avoiding blame
  • Using data, prototypes, or small experiments to resolve subjective disagreements
  • Escalating or bringing in a neutral third party only when necessary and transparently
  • The specific outcome and how the working relationship improved or was maintained
  • A lesson learned about communication style, timing, or when to concede
