How much does a MAC make-up artist make....I live in Alberta Canada?

I am going for my third interview for a counter position for a part time MAC cosmetics girl. I have 5 years of on counter experience, certified in make-up artistry, and at one point of my life was a former counter manager of another line. We haven't discussed wage yet, but does anyone have any ideas? I live in ALberta, Canada. Also any hints or tips to get the job with my interviews coming up???How much does a MAC make-up artist make....I live in Alberta Canada?
I don't know exactly how much you would make hourly, but I know a lot of it has to do with how much makeup you sell in a day.. You have to reach a certain goal for your sales. And if you don't make the goals that are needed to be met, then you'll usually get fired because everything is based on how much products you sell!!
