Your question is Explain Cross-Tab Pivoting in SQL. 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).
You are asked to explain what a cross-tab or pivot operation does to someone with no Excel or database background. Your explanation should make clear how the data changes shape, why the transformation is useful, and what happens when multiple rows map to the same output cell.
A pivot is a common reporting pattern in SQL and analytics tools, including Alteryx workflows that prepare summary tables for dashboards. The interviewer wants to hear whether you can translate a technical transformation into plain language.
