It took them 6 months to call me back just to put me into a group interview. Dress however you want as they will hire anyone off the street (seriously some of the employees speak little to no english at all). The humans resources person that will conduct the interview will tell you how amazing this company is to work for with opportunities for travel and raises every 6 months and great benefits. Unfortunately none of this is actually true except that you are guaranteed a raise every 6 months and these raises are usually around the .05 to .10 cent range. And no do not ask to talk money with these people because all their employees make a fixed hourly rate. You will need to complete a physical agility test which will consist of you lifting a few 40 lbs. bags. They will ask about your medical history and then drug test you. This is not a pee test.
