Interview Prompt
The content team wants the most-watched content overall. A view counts toward a piece of content when a page view's user matches that content's creator (treat any page view by a creator as a view of all their work). Sum the page view durations to get each content item's lifetime value. Rank by lifetime value descending, allowing ties to share a rank. Return the top three ranks, with content ID, title, and lifetime value.
Summary
Lifetime value. Measured in total watch time.
