The process took 1 day. I interviewed at Giant Food in Feb 2007
Interview
They just wanted to know about me, basically. Largely behavioral interview with little technical content. Manager seemed very friendly and accomomdating. Advice: be yourself, emphasize your strengths that apply to being a cashier (friendliness, quantative quickness, etc.).
Interview questions [1]
Question 1
Why will our customers feel comfortable dealing with you?
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.
