I was charged with marijuana possession back in November 2012 and the outcome was Nolle Prosequi. Haven't had a chance to expunge it yet. Now I am in the process of being hired by FedEx and will apply for CDL training as well (interview and drug test passed). What should I expect from background checks? Can companies' reject me an employment on basis of "Nolle Prosequi" on drug charges? Please advise. Thanks.
