DevOps Engineer Interview Questions
10 questions with tips and sample answers for remote job interviews in 2026.
1 technical Walk me through how you would set up a CI/CD pipeline from scratch.
What to include: Lint → unit tests → build artifact → integration tests → staging deploy → smoke tests → production. Mention rollback mechanism.
Practice this question with AI feedback →2 technical How do you handle secrets management in a cloud environment?
What to include: AWS Secrets Manager, HashiCorp Vault, or GCP Secret Manager. Never in env vars baked into images. Rotation policy.
Practice this question with AI feedback →3 behavioral Describe a major incident you were on-call for. How did you respond?
What to include: Timeline: detect → acknowledge → communicate → mitigate → resolve → post-mortem. Show blameless culture.
Practice this question with AI feedback →4 remote How do you do on-call handoffs across time zones?
What to include: A structured handoff doc (open incidents, recent changes, anything to watch), a shared runbook, and an overlap window for questions.
Practice this question with AI feedback →5 technical What is your approach to infrastructure as code? What tools do you prefer and why?
What to include: Terraform for cloud infra, Helm or Kustomize for Kubernetes. Explain why declarative > imperative. Mention state management.
Practice this question with AI feedback →6 situational An engineer wants to deploy a change directly to production without going through CI. How do you handle it?
What to include: Explain the risk (no audit trail, no rollback, breaks reproducibility), then offer a fast-track path through CI that meets their urgency.
Practice this question with AI feedback →7 technical How do you design a monitoring and alerting strategy that avoids alert fatigue?
What to include: Alert on symptoms (SLOs) not causes. P1 alerts must be actionable. Use error budgets. Reduce noise by routing low-severity to a dashboard, not a page.
Practice this question with AI feedback →8 behavioral How do you balance developer velocity with operational stability?
What to include: Show you see it as a spectrum, not a trade-off. Good pipelines make fast and safe synonymous. Feature flags and canary releases help.
Practice this question with AI feedback →9 remote How do you document runbooks and architecture decisions for a distributed team?
What to include: Written runbooks in a shared wiki (Notion, Confluence), ADRs for significant decisions, and Loom walkthroughs for complex topology.
Practice this question with AI feedback →10 technical Explain the difference between horizontal and vertical scaling. When do you choose each?
What to include: Vertical = bigger machine, simpler but limited. Horizontal = more machines, needs stateless design. Most modern cloud workloads target horizontal.
