Behavioral + Technical Leadership: End-to-End Project and Production Bug
Provide a recent, specific example of a project you led end-to-end. Use one concrete incident to show how you diagnose and fix a difficult production bug.
Cover the following:
-
Project overview
-
Goal, scope, and your role/ownership
-
Key stakeholders and constraints (SLA/SLO, scale, compliance, deadlines)
-
Production bug context
-
Symptoms and business impact (who/what was affected, severity, timeline)
-
How it was detected (alerts, dashboards, user reports)
-
Debugging approach
-
Initial hypotheses and how you prioritized them
-
Instrumentation/probes you added (temporary metrics, logs, traces, feature flags)
-
Specific logs/metrics/traces you used and what they showed
-
Any reproduction steps in lower environments
-
How you isolated the root cause
-
Fix and verification
-
Code/config/data changes
-
Tests added (unit, integration, e2e, chaos/fault injection)
-
Release strategy (feature flag, canary, rollback plan)
-
Monitoring and success criteria used to verify the fix
-
Trade-offs and alternatives
-
What you chose and why; what you deliberately deferred
-
What you'd do differently next time
-
Process/architecture/observability improvements you would make
-
Feedback and growth
-
How you incorporated feedback from peers/stakeholders and how it helped you operate at the next level
