Given a products table (listings) and a transactions table (bids), write a query that returns each listing's bid count, highest bid amount, and the user who placed it. Listings with no bids should still appear with a count of 0 and NULL for the bidder.

  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
