DevOps Engineer interviews — common questions
- Who is this DevOps Engineer interview plan for?
- It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the CI/CD Pipeline Discussion round for a DevOps Engineer role. It gives you a 60 min script to follow in the conversation — 3 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.
- What does the CI/CD Pipeline Discussion round assess?
- This round is focused on: CI/CD Pipelines, Deployment, Version Control, Testing Automation, Monitoring. It works through CI/CD Pipeline Challenge and Closing, scoring against 19 observable signals, with follow-up prompts on all 3 questions for going deeper where an answer is thin.
- How is the 60 min split up?
- CI/CD Pipeline Challenge (50 min), Closing (5 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.
