Interview Prompt
We manage cloud infrastructure for thousands of enterprise customers across AWS, Azure, and GCP. Every customer wants a single unified view of their cloud spend, but each cloud provider delivers billing data on a different schedule with a completely different schema - AWS Cost and Usage Reports are hourly CSVs, Azure exports daily JSON, and GCP streams near-real-time. Design a pipeline that unifies these into a consistent cost analytics layer and alerts us when any managed account is trending toward a budget breach.
Summary
AWS, Azure, GCP. Three bills. One truth.
