Explain CI/CD and what a typical pipeline includes
Reported in TeamViewer European engineering loops. DevOps fundamentals for mid-level engineers discussing automation and quality gates.
Interview scenario
Often asked in TeamViewer loops at European offices (London, Berlin, Amsterdam, Paris, Stockholm, Dublin, and remote EU). Prepare a clear spoken answer plus key trade-offs.
Model answer
Try answering aloud first
Cover trade-offs, structure, and a concrete example before revealing the baseline response.
How to frame this at TeamViewer: Connect your answer to measurable impact, clarity of thought, and trade-offs the team cares about. Below is a strong baseline response you can adapt with your own project examples.
Continuous Integration (CI): developers merge frequently; each push triggers automated build, unit tests, lint, and security scans. Goal—catch defects early.
Continuous Delivery/Deployment (CD): artifacts deploy to staging/production automatically or with approval. Delivery keeps manual prod gate; deployment goes fully automated with feature flags.
Typical stages: checkout → dependency install → compile → test (unit, integration) → static analysis → build container image → push registry → deploy to k8s/ECS → smoke tests → notify.
Best practices: trunk-based development, ephemeral preview environments, rollback strategy, secrets in vault—not repo, and DORA metrics (deployment frequency, lead time, MTTR, change failure rate).
