Tell Me About a Time You Strongly Disagreed With a Peer's Technical Decision
Behavioral and LeadershipConflict and InfluenceAsked atMidSeniorUpdated
“Tell me about a time you strongly disagreed with a peer's technical decision. How did you handle it?”
They're checking whether you can disagree about the work and keep the relationship. Strong answers show you understood their reasoning first, made your case with evidence, and owned the result either way.
Rubric by Level
Junior
- Raised the concern with your peer directly and kindly.
- Asked why they chose it before arguing.
- Brought something concrete, like a failing case or a quick benchmark.
Mid
- Names the decision and what was at stake, like latency, correctness, or scope.
- Tested your own view first, and admits where it was weak.
- Made the case with data or a prototype.
- Committed to the outcome and can say what you learned.
Senior
- The decision affected a system you shared, and you weighed the cost of being wrong both ways.
- Escalated to a tech lead only after a direct conversation, and framed it as a decision to make.
- Owns the outcome whether or not your view won.
- Describes how the relationship held up afterward.
Principal
- The decision had multi-year consequences for the company's architecture.
- Kept the people separate from the problem when the peer was another senior leader.
- Shows how you set norms for how technical disagreements get resolved.
Red Flags
- Frames the peer as wrong/incompetent rather than the decision as suboptimal.
- Vague resolution like 'we eventually agreed' without describing how.
- No reflection on what you'd do differently.
Follow-Ups to Expect
- What did you do when leadership sided against you?
- How did the relationship evolve after?
