AI Engineer Interview Preparation #
Are you taking prep for your upcoming interview?
1.** A product team is building an AI assistant that can answer support questions, look up live subscription status, create refund requests, and update customer records. During architecture review, one engineer suggests letting the LLM directly decide and perform every operation once the user asks. For a large-scale production system, what is the safest boundary between the model and real business systems?**
