That whole “Google cares about GPA even for people 
  years out of college” thing?  I supposed I can’t 
  speak for every hiring committee, but I never 
  remember my hiring committee discussing the GPA 
  of a professional candidate.  For that matter, 
  we were never even given a candidate’s GPA unless 
  he/she elected to put it on their resume.

This doesn't jive with what I know of the process. Tom Galloway's response in the comments, however, does:

  GPA/SAT/GRE: Perhaps not in Engineering so much, but 
  a *lot* of non-Eng HR and HCs did do cuts based on what 
  school someone attended and/or their GPA and test scores. 
  And I know for a fact that even Eng applicants who had 
  been out of school for over a decade were asked for such 
  on a regular basis. There were a number of us, mostly 
  older types, who semi-actively campaigned against Google 
  asking for such from folk who’d been out of school for a 
  while as we felt it 1) was useless relative to their 
  actual job performance and 2) it was embarrassing *to* 
  Google for us to ask for such irrelevant info and gave 
  up a bad impression/rep.
