Interview Prompt
The search quality team wants to measure how often users click a result when the result set is small. In a single row, compute two percentages relative to all search records: the share of queries where a result was clicked and the results count was 3 or fewer, and the share where no result was clicked despite the results count being 3 or fewer.
Summary
Some searches lead to clicks. Most do not.
