Your question is ETL/ELT Technology Choices. 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).
Which technologies have you utilized for building ETL/ELT pipelines, and why?
Describe the technologies you have personally used for ingestion, transformation, storage, orchestration, and data quality. Explain the trade-offs behind your choices, including batch versus streaming, reliability, scalability, observability, maintainability, and cost. Include one representative pipeline, its failure-handling approach, and how you would test and monitor it in production.
