Interview › Resume & Behavioral
Describe a time you disagreed with an architecture or technical decision - how did you handle it?
Resume & Behavioral · Basic level
Answer
When I disagree or need to push back, I make the risk explicit and keep the conversation collaborative. I first understand the goal and constraints, then present data: reliability impact, security exposure, cost, blast radius, reversibility, or operational complexity. I try to offer options instead of only saying no: phased rollout, feature flag, canary, reduced scope, extra validation, or a different timeline. Once a decision is made, I commit to execution while tracking documented assumptions and risks.
Technical explanation
Constructive disagreement is based on evidence and trade-offs, not personal preference.
Senior SREs protect reliability by framing risk in business terms: customer impact, data risk, compliance, recovery time, and cost.
Disagree-and-commit means support the chosen path, but revisit if new evidence changes the risk profile.
Hands-on example
1. Create a lightweight ADR with options, pros/cons, risk, cost, timeline, and rollback implications.
2. If the request is unsafe, propose a safer path: canary, feature flag, staging validation, limited cohort, or rollback test.
3. Document the final decision, owner, assumptions, go/no-go criteria, and metrics that would trigger reconsideration.
