90% of Kubernetes interviews in 2026 come down to these 7 points. Can you explain them without buzzwords?
1. Pod vs Deployment vs StatefulSet: when you need stable identity, volumes, rollouts, and why
2. Services DNS: ClusterIP vs Headless vs LoadBalancer, and how traffic actually reaches a pod
3. Requests/limits: scheduling vs throttling vs OOMKilled, and how you size for spiky workloads
4. Probes: startup vs readiness vs liveness, and what breaks during deploys if you misuse them
5. Config secrets: env vs volumes, reload patterns, and what not to put in etcd
6. Ingress gateways: TLS termination, path routing, timeouts, and where mTLS usually lives
7. Debugging: kubectl logs/exec/describe/events, ephemeral containers, and reading why a pod is Pending or CrashLoopBackOff
