What does a FedEx employment background check include?

Basically everything. Previous addresses, work history, family, police record, d,v record, you name it. It is federal job, hence federal express (FedEx) . However they do make mistakes. Well, the agencies that do the background checs make mistakes, they accidentally put on my application that I had pending charges in all couties I ever lived im. I called all the counties to see if they had anything in their databases and they said nothing. They even confirmed that they snail mailed statements to fed-ex stating I am clear. Lol, sorry for the babble. I just hope you double check their check on you. It will mean getting or loosing your job.
