Interview Prompt
We're auditing our release cadence, where each successful production deploy of a service stays live until the next successful production deploy of that same service replaces it. For every release that was eventually replaced, report the service, the version, and how many calendar days it stayed live, longest-lived first.
Summary
Every deploy stands its post until the next one arrives. Find the ones that stood longest.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your sql solution with real code execution
- Get instant feedback and a hire/no-hire decision
