I have hired a number of my own employees and have helped with the hiring of our class of new officers for about 12 years. I have been fortunate with my own choices with only one that I sometimes wonder about. What we do is not perfect and is very much restricted by state law. When I can, I use whatever outside resources I am allowed.

My experience has been that there are many who might be able to the job, but only those who really WANT to do a good job will be inclined to do it as well as you would like. It is uncovering the true motivations that will make your decision easy.
Good luck!
