Welcome to your interview.
The question is on your right: Infrastructure as Code Benefits. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You're joining a team that builds and runs data pipelines, and you want a consistent way to provision pipeline infrastructure across environments.
Explain the concept of Infrastructure as Code (IaC) and its benefits.
