What if · the follow-ups in this answer

The answer works through 4 follow-ups like an interviewer would

A fictional support assistant has a candidate detector with 190 of 200 attack cases flagged and 20 of 1,000 benign cases flagged in a selected test. The team needs an operating decision, not just a percentage.

  1. Ten of two hundred test attacks are missed. Are ten breaches confirmed?
  2. A mandatory response check times out after streaming begins. What should be reviewed?
  3. Blocking rejects important troubleshooting documents. Should the entire detector be discarded?
  4. What would you approve, conditionally?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Sign in free to open it.
