Federal Reserve Board

One Bill Across Three Clouds

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.

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.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your pipeline design solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
