T o be honest,it can take who knows how long
When I hired on in 1991 I tested and interviewed in March,had a background check and was given my physical in early May,then hired June 18th.
So if you have gotten this far and you fill good about your physical and have a good police and driving record,I wouldn't worry too fast.These things sometimes takes a little time.
Good Luck .
