Your question is Batch Pipeline with Schema Drift. 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).
Design an end-to-end architecture for a batch processing system handling schema drift, SCD, data modeling, and optimizations.
Asked in the Technical Round 2 (System Design) stage. Focus on how you would keep batch pipelines reliable as source schemas change, slowly changing dimensions evolve, and downstream models stay performant.
