Thank you all.

Well, so the truth is, I told them I have two plus years of ecommerce experience in the interview, which I do. Thing is, that that experience didn't amount to me learning a whole lot about how ecommerce works... but that wasn't the focus of the conversations.. my general knowledge and other experience was.

One of the tasks they're asking me to do is not in the job description, but I said I could do it when he asked. It is copywriting for a website, and I do have some amount of copywriting experience, just not in this way. The other task is a more typical like task for my field that I've never done before.

I will think about what questions I can ask that don't make it seem like I don't know what I am doing.

Seesaw, those are some great suggestions, thanks! I will do just that.
