Interview Prompt
The release manager is benchmarking how often each service ships. For each service, average the gaps in days between its consecutive deploys, then return the service name and its average gap.
Summary
Days between deploys. Some services ship fast, others crawl.
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
