CI/CD
Also written as Continuous Integration, Continuous Deployment, Continuous Delivery
Automated pipelines that test and deploy code changes frequently and reliably, instead of manual, infrequent releases.
Think of it like
Like an assembly line with automatic quality inspectors at each stage, so a finished product rolls out the door the moment it passes, without someone hand-checking each unit.
Junior or senior?
Junior sounds like
Has only used a CI/CD pipeline someone else set up.
Senior sounds like
Has built or maintained one from scratch.
Ask them
“Have you set up a CI/CD pipeline from scratch, or only worked within an existing one?”
Sounds like real experience
Describes a specific pipeline stage they built or fixed — a flaky test that blocked deploys, a caching step that cut build time, a rollback mechanism — not just that pipelines exist.
Probe further if
Describes using a pipeline — pushing code and watching it go green — without describing configuring, debugging, or changing any stage of it themselves.
