What if · the follow-ups in this answer

The answer works through 6 follow-ups like an interviewer would

An engineering organisation wants security built into how AI features are developed, from idea to operation.

  1. What happens at the idea stage?
  2. What happens at design?
  3. What happens at build?
  4. What happens at test and release?
  5. What happens in operation?
  6. How would you build the secure SDLC?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
