For each transaction, show the transaction ID, username, the transaction amount, and the ratio of that transaction's amount to the user's overall total as a decimal. Each username is unique and each user has at most one transaction per day.

  1. Read the vague prompt (just like a real interview)
  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
