CI/CD mock interview
A four-question CI/CD screening interview. A senior engineer digs into how you ship: pipeline design, flaky tests, slow deploys, and the automation that bit you.
what this interview covers
- Slow deploys and batching
- Flaky tests
- Designing the path to production
- Deploys that lie to the dashboards
- Automation that bit you
How the interview works
4 questions, 1-2 follow-ups each. The interviewer will not confirm or correct anything until the debrief. You can say you do not know and move on - that beats bluffing. End early if you must; fewer than 3 answered means no verdict, but you still get per-question feedback.

About
This is a screening interview for the delivery side of DevOps: how code you write becomes code in production, and what happens when that path breaks. Expect four questions drawn from a bank of five, covering pipeline design, flaky tests, slow deploys, deploys that pass every check while users suffer, and at least one question about automation that has actually bitten you. The interviewer probes the way a real one does - if your answer stops at "add caching" or "use canaries", expect a follow-up asking how, exactly.
The interviewer will not tell you how you are doing. No "good answer", no "not quite" - just neutral acknowledgments and the next probe, whether your answer was excellent or completely off. That is deliberate: real interviews withhold feedback, and learning to read your own answer quality without a reaction is part of the skill. If you do not know something, say so and move on. Passing on a question grades as uncovered ground, never as a red flag - bluffing is what interviewers actually punish.
The debrief at the end shows everything the interviewer was holding back: which points a senior answer hits and whether you covered them, what you only reached after a nudge, anything an interviewer would quietly note as a concern, and a written senior answer to each question you faced. Retake the interview and it rotates in the question you have not seen yet, so a second attempt is not a rerun.
