Performance Optimization and Incident Response Questions

Identify and remediate performance bottlenecks while maintaining disciplined incident response. Topics include profiling and tracing latency sources, database tuning and query optimization, effective use of caching and content delivery techniques, capacity planning and autoscaling strategies, detection and alerting for degradation, incident response playbooks and escalation paths, and post incident optimization and verification. Candidates should be able to demonstrate measurable improvement approaches and a repeatable response process.
