How does it work for Google? Except for the "search+ads" division, which seems too important to ruin, Google gives the impression of a highly unfocused company with internal feuds and fiefdoms that releases one half-baked product after the next.
It seems to me that Google only hires to keep people from working for the competition.
I think you might be greatly underestimating the fraction of the company that works on search or ads if you think you can make a meaningful comment about the company that starts with "Except for the 'search+ads' division."
