Knowing people who are managers or supervisors really streamlines the interview process. I was good friends with the manager's son, and he vouched for me to the HR department, effectively insuring that I would get hired. As for the process itself, the HR desk attendant will give you a form to fill out (basically a resume), and then you will speak to a representative who will ask you various questions concerning your school situation, your preferred hours, etc. For a simple packaging job, the process is fairly simple.
