Ozark Motor Lines questions...

So I'm about to be in my 2nd week of CDL school and I have been extremely interested in going to Ozark Motor Lines based out of Memphis after graduation. (just sounds like a good company. I went online, filed out the application and noticed they only ask about felonies and only for 3 years for traffic citations.Here's my question... I have traffic infractions from 4 and 5 years ago, so didn't list them on the application. Also, I have a misdemeanor Possession of a Firearm from 4-5 years ago, so also didn't list that. Is this going to cause me issues with them? I spoke with the recruiter today and they are setting up an orientation date, Greyhound ticket, and beginning my background check today. If they didn't ask on the application what is the likelihood they'll send me home from orientation for things outside their application? Thanks. Also if anyone has any insight into Ozark's orientation please let me know.
