Everything was through email communication until you have the first interview after a basic math test. Two weeks of theory training about fueling aircrafts, FAA documentation etc. When I use to work for the company there was only one to two weeks of training on the field but after a couple of months the "management" was asking for 3 weeks to be sure that you learn enough to work alone in a "truck". Your trainer is one of the regular fuelers and after you've been sign off you go to a schedule bid to get your shift that 60% of the time is during the night unless one of the lines are open because of the constant turnovers situation. After that be ready for mandatory overtime of 16 hours at least twice a week. After three months you became part of the Union (always keep an Union book with you, your were gonna need it)
