Interview Prompt
For each service, we want to know what percentage of its alerts are high or critical severity. Surface only the services where more than half of the alerts qualify, report that percentage rounded to one decimal, worst first with ties broken by service name.
Summary
Not every alert deserves a 3 a.m. page. Find the services where most of them claim they do.
