Interview Prompt

Our alerting system logs resolution times. For each month, calculate the percentage of resolved alerts where resolution took more than 20 minutes beyond the predicted time. Format months as 'YYYY-MM'. Return the month and late percentage.

How This Interview Works

  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
