Welcome to your interview.
The question is on your right: Data Profiling in ETL Pipelines. 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 working on a new pipeline and want to understand the data before building transformations and downstream models. You need a practical way to inspect source quality, spot anomalies, and document what the data looks like over time.
What is your experience with data profiling techniques?
