Google contracting?

Interviewed at Google a couple of months back (onsite) for a FTE position and got rejected for reasons they weren't willing to discuss. My understanding is that I'm in the cooling off period of interviews now. That said, I now have (third party) recruiters trying to get me into a contract role with them, but I can't help but feel a little...chagrined? Annoyed? Cheated? Hard to say. I was really looking forward to actually having insurance and being able to leave the contractor life. So my questions are: 1. Is it worth following up with any of these recruiters? 2. Does being a contractor hurt chances of FTE later? 3. How is the contractor = second class citizen thing? (It grinds on me pretty hard at MS.) I like my team at MS, but they've made it plenty obvious I'm forever a contractor here, too. @Google
