Interview Prompt

A release engineer sweeping `feat_flags` before the next rollout wants to know: which owners are holding flags with no rollout value on file, how many such flags does each hold, and how many of those are switched on anyway?

Summary

Which flags are actually live?

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
