I had an offer for something more suited to my skills before I left Google, skills that I knew Google would ultimately need, but didn't yet need when I was there. In fact I had previously turned said offer down to join Google in the first place. These employers were happy to have me. All is good there.

What isn't so good is that since I left Google, several positions have arisen that would very much make use of my existing skill set. Several people within have tried to get me considered for those positions only to get shut down by HR without so much as a phone screen. So I would appear to be on some sort of black list. There are worse things in life, but it does seem silly to me.
