Interview Prompt
The SRE team is hunting compound failures: the records where several independent alarms trip at once. Surface every error record where at least two of these markers appear: 'Error' in the type name, 'null' in the message, 'api' in the service name, or a severity flagged as an error.
Summary
The worst failures never arrive alone.
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
