The Pain and Agony of Hiring New Employees

I hear at least one of these daily…..

Why is there so much pain and agony in hiring new employees?
They interviewed perfectly, then turned out to be terrible.
I have no idea what questions to ask.
We need someone now!
We needed someone right away then hired the wrong person.
They just didn’t fit.
What did HR see in this person?
What did the hiring manager see in this person?
Can’t I just give them some sort of test?

While this does not even come close to all the complaints, it is a list of some more common ones.
