Welcome to your interview.
The question is on your right: ETL vs ELT Trade-offs. 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 discussing how to structure a new data pipeline and need to choose where transformations should happen. The goal is to compare the two common patterns and understand when one is a better fit than the other.
Explain the difference between ETL and ELT approaches. In what scenarios is ELT preferred?
