Your question is Ingesting Frequent Event Data at BNSF. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Given a document of functional and non-functional requirements for a backend related to BNSF operations that ingests frequent event data, propose and discuss the design (e.g. queueing events before backend processing).
Asked in the system design round stage. Discussion only, no code. Explain how you would clarify missing requirements and design reliable ingestion, processing, storage, and optional ML enrichment without assuming undocumented product details.
