Interview Prompt
We run a content platform with a built-in team chat, and we want to recommend pages a person hasn't opened yet. Treat two people as connected when they've both posted in the same chat channel, and for each person surface the pages their connections have viewed but the person themselves never has.
Summary
Pages they haven't discovered yet.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your sql solution with real code execution
