Your question is Resolving Conflict Between Senior Engineers. 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 handle a strong disagreement between two senior engineers on a technical approach. How did you help the team reach a decision, and what did you do to preserve trust and execution afterward?
