Interview Prompt

The feature flag dashboard needs a clean boolean representation for downstream consumers. For each flag, show the flag name, a 1/0 indicator for whether it is enabled, and a 1/0 indicator for whether it is disabled.

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
