Interview Prompt

Each row of cloud_costs is one billed charge from AWS, GCP or Azure, and only the GCP and Azure invoices are being reconciled. List the charge amounts on those invoices.

Summary

AWS, GCP, Azure. Side by side.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
