Interview Prompt

Capacity planning is evaluating whether to add nodes in specific regions, but they only care about regions that are actually running workloads. Using the pod assignment records, show the average CPU utilization of nodes in each region where at least one pod has been scheduled.

  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
