Interview Prompt
In our multi-tenant Kubernetes cluster we hunt the noisy neighbor in each namespace: the pod using the most memory. Some pods are still starting up and haven't reported memory yet, so ignore those and list each namespace's top consumer with its memory, heaviest first.
Summary
In every namespace, one pod does most of the eating.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your sql solution with real code execution
- Get instant feedback and a hire/no-hire decision
