Interview Prompt

The engineering manager noticed that some long-tenured contributors still get heavy review feedback while newer ones sail through. For each author, pull the average number of comments on their code reviews alongside the date of their earliest commit. Present results starting from the most tenured author.

  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
