Interview question · Software, Data & Model Supply Chain

What security tests would you run before every model update ships?

A model update can quietly undo controls you rely on. The scored answer runs a fixed security suite with thresholds agreed in advance, checks the artefact too, and decides what blocks a release.

What if · the follow-ups in this answer

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

A team wants to upgrade the model behind its customer assistant, which reads tickets and can issue refunds, to a newer provider version next week.

  1. Why is a model update a security change?
  2. What do you verify about the artefact?
  3. What should the regression suite cover?
  4. How do you compare old and new models?
  5. What if the new model is better overall but worse on one injection channel?
  6. What pre-release process would you set?

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.
