Your question is Continuous Integration Basics. 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).
Do you have notions about Continuous Integration (CI)?
Explain how you would apply CI to an ETL pipeline, including code validation, unit and data quality tests, dependency checks, and deployment gates. Provide a practical implementation using a tool such as GitHub Actions, with attention to reproducibility, failed builds, and safe Airflow or dbt changes.
