Interview Prompt
We're studying the first impression our product makes, so for each visitor we look only at the earliest three pages they opened, in the order they viewed them. Across all visitors, surface the pages that appear most often in those opening views, keeping the three most common and any page tied at the third position.
Summary
The first three pages decide who stays.
