Your question is CI/CD Pipeline From Scratch. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You can describe a scenario where you needed to implement a CI/CD pipeline from scratch. What tools did you use, and how did you ensure security and scalability?
In a practical response, explain the pipeline from source control through testing, artifact creation, deployment, and production monitoring. Address how data pipeline changes, infrastructure, secrets, access controls, rollback, and parallel execution would be managed.
