Your question is Building Consensus on Architecture. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to advocate for a technical architectural change; how did you build consensus? Please describe the decision, the stakeholders involved, the evidence you used, and how you handled disagreement. I am looking for influence without authority, thoughtful trade-off analysis, and ownership of the outcome. A strong answer should use a specific example, explain how your position evolved through discussion, and include the result and lesson learned.
