Interview Prompt
An engineering manager is auditing which repositories have gone quiet, where a repository's longest silence is the widest stretch of days between two back-to-back commits. For the repositories with a long track record, report each one's longest silence with its standing, most silent first.
Summary
Some codebases stop speaking for too long.
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
