Overview
DevOps interviews often focus on real‑world problem solving rather than textbook definitions. To help candidates prepare, a GitHub repository — devops‑cloud‑interview‑scenarios — was created with practical scenarios, the skills being tested, structured answer guides, and follow‑up questions that interviewers typically ask.
Example Scenarios
| Situation | What the interviewer is testing | Structured answer | Follow‑up questions |
|---|---|---|---|
| Your team just migrated a monolith to microservices on Kubernetes. Two weeks after go‑live, intermittent latency spikes appear with no obvious pattern. How do you approach this? | Troubleshooting distributed systems, observability, and performance analysis on Kubernetes. | Identify metrics, check service meshes, review logs, isolate problematic services, reproduce the issue, propose mitigation. | “What tools would you use to pinpoint the source?” “How would you communicate findings to stakeholders?” |
| A Terraform apply is failing with “Error acquiring the state lock.” Another engineer says they didn’t run anything. What do you do? | Understanding of Terraform state management, concurrency, and lock handling. | Verify lock holder, inspect remote backend, manually unlock if safe, implement locking policies, add CI checks. | “How would you prevent this in the future?” “What are the risks of force‑unlocking?” |
| Your CI pipeline is passing but the production deployment is failing silently — the pods start, pass health checks, then crash ten minutes later. Walk me through your debugging approach. | Ability to diagnose deployment issues, interpret pod lifecycle events, and use monitoring tools. | Review pod logs, describe events, check resource limits, examine liveness/readiness probes, trace recent code changes, roll back if needed. | “Which observability tools would you use?” “How would you ensure zero‑downtime rollback?” |
The format for each entry includes:
- Situation – the scenario presented to the candidate.
- What the interviewer is really testing – the underlying competency.
- A structured answer – a step‑by‑step approach.
- Follow‑up questions – deeper probes an interviewer might ask.
How to Use the Resource
- Search: Type keywords such as
crashloopbackoff,terraform state lock, orprometheus scrapeto instantly locate relevant scenarios across the entire collection of 770+ questions. - Device compatibility: The site works best on a laptop; mobile experience is limited at the moment.
- Android app: An app is under review on the Google Play Console and will be released soon.
