Interview Prompt

During an incident postmortem, the on-call engineer needs to categorize error tracks into three buckets: those related to timeouts, those related to connections, and those related to memory. Each category should show its label and corresponding count.

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
