Something that can help you on the pre-trip...Go on google, and put in class 8 truck pre-trip inspection...It will bring you to some youtube videos of truck driving school instructors, doing a complete pre-trip.. Also, prepare for the interview, it is easy to get tripped up by a question if you are not prepared for it, something as simple as, "tell me about yourself", or "why should we hire you"..
I hope you get on, its a great place to work...I left an LTL carrier with 18 years of seniority to come to Walmart, and have no regrets..
