DevOps Engineer Interview Questions usually center on CI/CD, infrastructure, and troubleshooting questions � the patterns pulled from real hiring rounds on Redrob Skills, not generic filler you’ll never actually hear. Common questions include: “Walk me through setting up a CI/CD pipeline for a Node.js app.” “How would you troubleshoot a production deployment that’s failing intermittently?” “Explain the difference between containers and virtual machines.”

Interviewers are testing how you structure an answer under pressure as much as what you know, so prepare specific examples from your own experience rather than textbook definitions.
