Site Reliability Engineering Questions

Covers the principles, practices, and operational responsibilities for keeping production systems reliable while enabling ongoing feature delivery. Topics include balancing reliability and development velocity; incident response, on call operations, and incident management including post incident learning; observability, monitoring, and alerting; automation and tooling to reduce manual toil; infrastructure and platform design; application reliability engineering; capacity planning, performance, and scaling; service level indicators, service level objectives, and error budget management; reliability engineering culture and interactions with product and development teams; and the metrics used to measure reliability and performance such as availability, latency, error rate, throughput, saturation, time to detection, and time to recovery. Candidates should be able to describe typical operational tasks at entry and senior levels, reason about trade offs, propose architectural or operational improvements, and justify decisions with metrics; senior engineers are expected to show deep expertise in some areas and demonstrable competence across many domains.
