Interview Prompt

An analyst is building an engagement roll-up with no master user list to start from. Report every identified user found in `user_sessions`, `search_queries` or the `user_activity_cumulated` snapshots, with their total sessions, total search queries and most recent `last_active_date`.

Summary

Sessions plus searches. The full engagement picture.

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
