Interview Prompt
Service agents record a status for every health check, but different agents write the same state in different letter casing, so 'Healthy' and 'healthy' both land in the table as separate labels. Report the average check latency for each health status, treating casing differences as the same state, with the slowest states listed first.
Summary
The same state wears different casing. Read the latency behind each one.
