QA brings a unique perspective to chaos engineering: thinking about failure from the user's point of view. "What does the user see when this service is down?" is a QA question that SRE might not ask.
Strong answers position QA as a natural partner for chaos engineering: defining failure scenarios based on user journeys, validating graceful degradation, testing error handling and fallback behaviour, and verifying that monitoring and alerting detect the failures. Best candidates discuss how QA's systematic approach to edge cases complements SRE's infrastructure focus.
Forward-thinking QA skill. Candidates who see the connection between quality assurance and resilience engineering are thinking beyond traditional testing. Ask: "What failure scenario would you want to test first and why?"
