Interview Prompt
We want each staging deploy's version from deploy_logs as a plain number: drop the leading 'v' where there is one and the dots between the parts, and return it as an integer beside the service name.
Summary
The version number is buried in the log.
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
