Your question is Handling Unreliable Campaign Data. 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 found missing or anomalous data in a campaign performance dataset right before an important decision or review. How did you diagnose the issue, communicate the uncertainty, and still help the team move forward?
