I just got an interview scheduled at a roofing sales company in fayetteville. I do not know much about how the whole thing works. Is it hourly plus comission or am I paid only if I make a sale?

anyone who has done this, please give me some pro's and cons on the subject..

any information would help.

The job description says 3 sales per week minimum quota. Seems like a great job if it's something worth doing.
