Interview Prompt
We keep two independent logs for the web product: one row per session in the session log and one row per page view in the page-view log, and a single person piles up many of each. For every user who shows up in either log, report their total session time in minutes alongside how many different pages they opened.
Summary
Add up the hours, count the rooms they walked through.
