DevOps Interview Guide - Real interview questions collected from people who actually sat through DevOps, SRE, and Cloud engineering interviews in 2025 and 2026.

A cluster with monitoring tools installed is not the same thing as a cluster that is actually observable. Plenty of teams run Prometheus, Grafana, and a logging stack, yet still spend twenty minutes during an incident just figuring out which pod is failing, what changed recently, and whether the problem is isolated or spreading. The gap is almost never a missing tool, it is a dashboard that was never designed around the questions an engineer actually asks when something breaks. Building a dashboard that closes that gap comes down to four categories of information, and getting all four onto one screen is what separates a genuinely useful dashboard from a wall of graphs nobody trusts during an incident.

Kubernetes is not one flat pool of things to monitor, it is a collection of distinct resource types, and each one has metrics that only make sense in its own context. A service's relevant numbers are about traffic, a node's relevant numbers are about physical capacity, and a persistent volume's relevant numbers are about storage usage and attachment state. A dashboard that treats every resource the same way, showing generic CPU and memory panels regardless of what is actually running, misses the specific signals each resource type needs.

Services, pods, nodes, and deployments each need their own dedicated view rather than being folded into one another. Persistent Volumes and PersistentVolumeClaims are frequently left out of Kubernetes dashboards entirely, even though a PVC stuck in a pending state is one of the more common reasons a pod never reaches a running state in the first place. Structuring the dashboard around resource type first, rather than around a single generic metric set applied everywhere, means an engineer looking at nodes sees node-relevant numbers immediately, without needing to filter out panels meant for something else.

Metrics tell you the current state of a system, but they rarely explain why that state changed. Kubernetes emits events constantly, a pod being scheduled, a container being killed for exceeding its memory limit, a volume failing to mount, and these events are frequently the fastest way to understand what actually happened, faster than correlating a metric graph against a timestamp and guessing.

A dashboard needs a dedicated events feed, not just metric panels, because an event answers questions a graph cannot. Component status and configuration checks belong in this same category, a simple pass or fail indicator per component tells an engineer instantly which parts of the system are configured correctly and which are not, without needing to dig through raw configuration files during an incident. Pairing this with last change information, showing what was modified and when, answers the question that comes up in nearly every incident: what changed right before this started. Without that timestamp sitting next to the failure, correlating a deployment rollout or a config change to an outage becomes guesswork.

Pods and services are where most day-to-day debugging actually happens, and they need summary information dense enough to answer the first questions an engineer asks without opening a separate tool.

For pods, health, phase, and IP address cover the immediate questions: is this pod functioning correctly, what lifecycle state is it in right now, running, pending, or crash looping, and what address can it be reached at directly if needed. A health status shown as critical alongside a phase shown as running is itself a meaningful signal, since it tells an engineer the pod is technically up but failing whatever check defines its actual health, a distinction that matters a lot more than either field would on its own. Direct access to logs from the same view removes the step of switching tools just to see what the pod is actually printing.

For services, error rate, throughput, and latency are the three numbers that describe whether the service is doing its job. Error rate shows how much traffic is failing outright, throughput shows how much volume the service is actually handling, and latency shows how long requests are taking to complete. These three together are usually enough to tell whether a problem is about capacity, about a bad deployment, or about a downstream dependency slowing everything down, and having them side by side on the service view avoids needing to jump between three different panels to build that picture manually.

Metadata fields like labels, cluster name, namespace, owner, and age look like minor details, but they are what let an engineer trust that they are looking at the right resource in the first place. In a cluster running multiple teams' workloads across several namespaces, a resource named the same as another one in a different namespace is a common source of confusion during an incident, and the owner label is frequently the fastest way to know who to actually contact about a problem, rather than guessing based on a service name alone.

Age matters more than it initially seems, since a pod that has been running for four hours behaves very differently from a pod that just restarted thirty seconds ago, even if their current metrics look identical at the moment they are viewed. Related resources, ConfigMaps, Secrets, and Services tied to whatever is being inspected, close the loop by letting an engineer trace a pod's configuration and its network exposure without leaving the dashboard to go search for those objects separately. A pod that is crash looping because of a missing ConfigMap key is far faster to diagnose when that ConfigMap is one click away rather than a separate kubectl command to remember and run.
