Interview Prompt
The on-call lead wants a scorecard with one row per service that has pods in pod_assignments, showing how many pod assignments it has and how many alerts in alert_events fired for it.
Summary
Deploys vs. alerts. One row per service tells the whole story.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
