I douibt that most carriers would give you an offer letter. Most won't even check your references until you get to orientation. They may do the basic DAC, but other than that they don't normally do much prior. They have too many who never show up at orientation, so they don't want to spend the money until you get there.
The problem with the "two weeks thing" is a lot of companies out there when you say you are giving them two weeks....they will send you out for 5 weeks...lol.
Yes, JB doesnt do a complete check until you get to orientation. But come on...in reality most people know their own history and know if there is something that is going to get them kicked out of orientation.
Still, JB...Meh. I worked in their corporate office for a long time. Yes, they have some good dedicated jobs, and their power only program seems to be a little better than the jobs I used to have to put drivers in. But There are surely better jobs out there. What are you looking for?
I don't want to work over 60 hours a week more then once a month if it can be helped but will do so if needed, prefer a 50-55 hour week, I would like to have a schedule of 4 days on 2 days off, I would like to be home in my bed every night, Time and a half/load and a half for all work on Sundays & Thanksgiving day, double time/double load pay on Christmas day, Quarterly bonus plan, along with a yearly bonus, 401 K with 6% company match, would like to make in excess of $60K and lets not forget a decent health and life plan, last but not least a company that believes in family... is that possible???
That is kind of a tough set of parameters for a full time job in trucking, ESPECIALLY, if you are new and have minimal experience.
You may be able to find a company that would hire you part time in that aspect once you have some solid verifiable OTR time.
Another factor to consider is your geographical area and the trucking companies and jobs in that area.
Best of Luck
