Interview Prompt
We suspect shoppers click less as the result list grows. Split every search in `search_queries` into small, medium and large by how many results it returned, and report each size's click-through rate as a percentage.
Summary
When search comes back thin, does the click still follow?
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
