Your question is Owning Multi-Source Data Accuracy. 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).
Tell me about a time you had to combine data from multiple disparate sources and were responsible for ensuring the final dataset was accurate and trustworthy. Walk me through how you validated the data, handled conflicting inputs, and communicated issues or trade-offs to stakeholders.
