01How would you standardize AI vs ML vs deep learning across multiple teams as a technical lead or architect?

A technical-leadership answer

Say this first: AI vs ML vs deep learning is a choice between approaches with different strengths. The useful answer is the decision rule, not a dictionary definition.

Use a real scenario

Imagine an internal support assistant that answers from approved policy documents. The team must decide how to apply AI vs ML vs deep learning, verify the result, and explain the user impact. For an AI Engineer, attach the explanation to an evaluation set and retrieval trace.

Show judgment

  • make the decision criteria visible across teams and create a safe default path.
  • Choose the option that fits the workload and constraints; do not present one option as universally superior.
  • Call out prompt injection and unsupported answers and the control that reduces it.

Evidence to mention

Track grounded-answer rate and p95 response time. Say what baseline you compared against, what would trigger a rollback or escalation, and who owns the follow-up.

request or change → guardrail / validation → AI vs ML vs deep learning → observable result → owner review

Practice prompt: Explain the escalation route when prompt injection and unsupported answers conflicts with delivery pressure.
