The original title is "Enterprise LLM Engineering Guide: Architecture To Interview Mastery"

Short summary

Enterprise LLM engineering moves beyond clever prompting to design production systems with reliability, security, observability, cost control, and access governance. The guide maps the field's evolution—from prompt engineering through RAG, agents, and MCP—and covers real use cases, best practices, and interview preparation for engineers building grounded, auditable, scalable LLM applications.

• •Enterprise LLM work is systems engineering around models, not just prompting
• •Field evolution: prompt engineering → RAG → agents → MCP → enterprise systems
• •Engineers focus on retrieval, observability, governance, security, cost control, and failure handling
