Unless Google has made their internal hiring notes and private information public, there's no data to be found on that. I don't know why you'd expect an opinion like that to have data to it when the opposite does not have data to it, either.

Also, be careful, logic as in item #1 is the same logic that companies use to justify any form of discrimination.

This is unfortunate, because hiring is one of the areas where a responsive, streamlined approach is most critical to acceptable outcomes. Creating a committee of irrelevant appointees to come in at a late stage and give an indirect evaluation based on the notes from two prior interviews only creates an opportunity to block good people w/ bikeshedding.

If someone whose company is getting acquired can't even get fast tracked out of this demeaning and silly process, it's no wonder Google turns off non-luminaries more interested in getting good stuff done than dealing with red tape and bureaucracies.
