You know, I know where you are coming from going from golden child to red-headed step-child. I know waaaayyyyy to well. As far as what to do about your job, going to the interviews doesn't bind you to a decision yet. It doesn't hurt to go and see what you think of the people, what they have to offer, etc. Maybe you'll go and decide they have nothing to offer you want, or you don't go and spend forever asking yourself "what if?".
