Worked for Fed X in the Past will it hurt ME???

Just wondering if this will hurt me or not, My buddy got me lined up for a contractor running for fed-x. I have did part time work as a warehouse employee for them like 4 or 5 year's ago, kinda just stop showing up after recovering from a bad cold, and some personal problems. So i was wondering i still have to fill out a fed-x app to get approved by them before the contractor can hire, think im in trouble??? Thank's
