The API observability team is building a traffic breakdown dashboard. For each combination of HTTP method and response status in the call logs, compute what share of total call volume that combination represents. Return the method, status, and the fraction as a decimal.

  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
