I think the outside world massively underestimates the viciousness of politics in the upper echelons of Google, and how it has been that way for a very long time. (It predates Sundar ascending to CEO). I have never worked for Google, but closely enough with teams and execs in those upper regions to know how the sausage is made and it forever soured me on possibly working there (and I believe that is entirely mutual). The post acquisitions which are not quite merged into the mothership teams tend to be on the receiving end of much of the worst, and it leads to the result where the survivors are the most obnoxious.

"Licking the cookie" has to be the single most common phrase that came up, but my general sense was that both Google and FB are full of weasels, only the latter is much more honest about it. Neither is particularly desirable.

EDIT: Feel the need to qualify, there is a lot of superb technical work there on many many teams, but it is the co-ordination of that (especially fights over gatekeeping that which goes forward) which is a total mess. The resulting strategic blunders and failure to execute create huge friction with the outside world.
