Everyone is friendly and helpful. No one is judgmental.
The other employees and atmosphere.
I don't have to go blind or die from gingivitis!
It was thorough and forced me to critically consider the interest I have in the type of work I would be doing.
They are kind, understanding, generous, and direct. If you do something right they acknowledge it. If you do something wrong they ask how they can help you improve. Wonderful people!
Getting the work done is a team effort and everyone has the same goal. Because of this, the work ends up feeling like getting together with friends to do a project.
