Description
DevOps and SRE Interview Questions and Answers basic to Advanced, Real-time Scenario-Based and Coding Based
DevOps and SRE summary
- Build strong foundations—Git workflows, CI/CD pipelines, Docker, Kubernetes basics, Linux, and IaC (Terraform/CloudFormation).
- Focus on automation, testing, basic monitoring (Prometheus/Grafana), secrets management, and participating in blameless incidents.
- Own services and platforms—advanced Kubernetes, service mesh, observability (tracing, high‑cardinality metrics), and SLO/SLI practice.
- Lead incident response, optimize costs, implement security at runtime, and improve developer self‑service platforms.
- Architect resilient distributed systems, run chaos engineering programs, design capacity planning and multi‑tenant platforms.
- Shape observability strategy, enterprise security architecture (zero trust, supply chain), and mentor technical leaders.
- Set reliability strategy and governance, align reliability with business outcomes, and manage large migrations and vendor strategy.
- Lead org design, executive communication on risk, and build culture and capability across engineering.
- Cross‑cutting: Embed SLO‑driven development, treat observability as a product, and converge security with reliability.
- Cross‑cutting: Balance cost vs. availability with formal decision frameworks and automate compliance and policy guardrails.
- Hiring focus: Use practical exercises for juniors, system design and SLO exercises for seniors, and strategy/architecture presentations for principals.
- Next steps: Convert bands into learning plans, interview rubrics, or tool‑specific mappings to operationalize hiring and development.
