Given users, user_sessions, and transactions tables, write a query that returns each user's name, total session count, and total transaction amount. Users with zero sessions or zero transactions must still appear in the output.

  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
