A DevOps interview question that tests whether candidates understand what actually happens when a container starts on a Kubernetes node. The key differentiator is knowledge of Linux namespaces, cgroups, and container runtimes — not just YAML configuration. The author claims 80% of candidates fail this question, implying most Kubernetes users lack deep systems knowledge.
