Interview Prompt
We run a content platform with a built-in team chat, and we want to surface pages a person has not opened yet but someone they talk to has. Treat two people as connected when they have both posted in the same chat channel, and for each person return the pages a connection has viewed that the person themselves never has.
Summary
Pages they haven't discovered yet.
How This Interview Works
