Quality Metrics and Measurement Systems Questions

Covers how engineering and product teams define, collect, and act on metrics that reflect system health and software quality. Topics include service level indicators and objectives, error budgets, reliability and uptime measurements, deployment frequency, lead time for changes, mean time to recovery and incident rate, code review turnaround, test coverage and test effectiveness, static analysis and linters, developer and team satisfaction metrics, and qualitative signals from retrospectives and customer feedback. Interviewers assess how candidates choose meaningful leading and lagging indicators, instrument systems and pipelines for telemetry, build dashboards and alerts, analyze trends to detect regressions or technical debt, prioritize engineering improvements, and measure the outcomes of interventions to drive continuous improvement.
