Well, you're better off filling out the information online. That way you don't get writers cramp. You're just one of many cattle to come to the slaughter house. Many times they put out a call for people to come in and you may wait 2-4 hours to be seen.
The questions are simple, if you breath through your nose, you most likely will be employed. The usual "What shift, what pay?" is asked. If you don't call in for one shift, you'd better have a good reason (Death would be passable) They really seem to be willing to cut their noses off to spite their faces by making it clear that you make a mistake they'll not employ you and thus THEY lose money.
