Platform Reliability and Operational Excellence Questions

Ensuring that deployment platforms are reliable, observable, and maintainable while minimizing operational cost. Coverage includes defining service level indicators and service level objectives, monitoring and alerting strategies, dashboards and health signals, incident runbooks and automation, capacity planning and headroom, safe upgrade and rollout strategies such as canary and blue green style techniques, resilience testing and chaos engineering, toil reduction and automation prioritization, continuous improvement processes, and measuring the operational impact of platform work. Candidates should be able to describe how they instrument platform health and how they reduce operational burden while preserving safety and velocity.
