I have mentioned it in job interviews before, because I'm applying to marketing related jobs and I don't have a whole lot of other job experience yet, so every bit helps. If I were to leave out everything under 1 year, my CV would have only 1 job on it, lol!
So far the people I brought it up to really seemed to liked it, it was all positive. I just use it to show them I'm truly interested in marketing because I spend my free time reading and learning about it too, using it for my shop.
Actually, the first time it was brought up was because the interviewer found my store by googling my name.. and I had never meant for her to find it. I didn't have any sales at that time, but still she was impressed just that I was doing this. In fact, she didn't notice that I hadn't made sales (they really don't look at our shop front the way we look at it ). Because of her liking it so much, I started bringing it up for other job applications.
