I applied in-person. The process took 4 days. I interviewed at Giant Food (Springfield, VA) in Oct 2011
Interview
basic interview questions about the job, dress well, be clean and dont talk like an idiot and you should be fine. its not a very serious job so you should be fine. I wouldnt stress about it.
Hiring process was pretty easy. It took about 30 minutes, and all the staff was very welcoming. I recommend getting there at least 15 minutes early. This shows properness and readiness.
Don't worry about it they'll just ask you why you want to work, and look at your background. They're usually hiring people on a daily basis so don't sweat it.
Why do you want to work here? What is your past experience? Have you been a cashier before? Situational questions as well as communications and team work effort sand ethics.
