Reliability and Incident Response Questions

Tests understanding of failure modes, fault tolerance patterns, monitoring and alerting, and structured incident management. Expect discussion of single points of failure, redundancy strategies, graceful degradation, observability approaches, runbooks and rollback procedures, incident triage and coordination, blameless postmortem practices, and how design choices affect mean time to detection and mean time to recovery. Candidates should be able to describe how to detect, recover from, and prevent recurring outages and how reliability objectives influence architecture and operational choices.
