Low production incidents, predictable scalability, and stakeholder confidence.
5. Scenario-Based Manager Round Questions
Scenario 1: Production Performance Outage
Question:
The application slows down severely after go-live. How do you respond?
Sample Answer:
I ensure immediate containment, support root cause analysis, review missed performance scenarios, strengthen load models, and implement preventive actions for future releases.
Scenario 2: Performance Defect Leakage
Question:
Performance issues are found in production that were not detected earlier.
Sample Answer:
I analyze coverage gaps, review assumptions, enhance workload models, and improve environment parity.
Scenario 3: Resource Shortage Before Release
Question:
Key performance engineers resign close to release.
Sample Answer:
I re-prioritize critical scenarios, activate backups, request interim support, and adjust timelines if required.
