Interview Prompt

An analyst is building the 2026 year-to-date activity summary for each user. It needs the minutes they spent in sessions, from `user_sessions`, and the number of different pages they viewed, from `page_views`.

Summary

Add up the hours, count the rooms they walked through.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
