Interview question · Software, Data & Model Supply Chain

What scans and admission policies would you require before an open-weights model runs in production?

Open weights arrive with code, configs, licences and unknown training. The scored answer turns due diligence into a repeatable gate that production enforces automatically.

What if · the follow-ups in this answer

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

Engineers keep pulling new open-weight models into projects from public hubs, and the company wants an admission policy enforced by the deployment pipeline.

  1. What should the policy require about source and pinning?
  2. What about file formats and code?
  3. What else must be reviewed before production?
  4. How is the policy enforced?
  5. What if a team needs a model quickly for an experiment?
  6. What admission policy would you implement?

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.
