In countries with “civil service examinations”, what is a “civil service” and why does it need an exam?

Question

I’m American so I don’t think we have any such thing so it’s hard for me to wrap my head around.

[The Wikipedia page](https://en.wikipedia.org/wiki/Civil_service?wprov=sfti1#) makes it sound like it’s all non elected government employees, but it’s hard for me to imagine a single exam that you need to pass to become a post office worker or a DMV worker or something like that.

You do need to take a test to work at the Post Office. They want to make sure you don’t mix up numbers, etc.
