Good luck to you. Is this a full time feeder position or are you going to be a seasonal. Either way just do your best on the road test. They are not terribly hard. Just make sure you double clutch when shifting. That is how all off the street hires and inside employees are trained to shift. After you pass the road test and get through two weeks of training with an On-Road supervisor you can float the gears till your hearts content. Just don't run over curbs on the test and make good turns. Follow all the road signs, posted speed limits, etc... That test will most likely be done in a 48'ft trailer.
Also in order to make book its 30 WORKING DAYS then probation is over. You will have to deal with a large amount of crap with weird hours. Progression is 4 years and believe me those years don't go by fast. If your in a large hub it won't be bad but will still suck to some degree. You will be called early in the morning or late at night.Good luck to you
