It doesn't match my experience. In almost seven years at Google I've worked on amazingly interesting projects - from hardware to user-facing products.
I've never once, in my entire time, had any level of management tell me that I should be worrying about selling ads or monetizing my projects. The consistent message has been "build great products".
So the notion that 99% (or really any majority) of developers at Google "drive the ad hive" is completely untrue - at least in my experience.
I'm a new hire, and I got assigned to somewhere that doesn't align with my interests, at all... other than the fact that it's "not front end."
Hoping switching is as easy as everyone says!
*Unless you're an acqui-hire, and then Google once again rocks because you get both the perks and the interesting work.
If I am in Gmail, it pops up the menu (but at the bottom, and not where the hamburger is). Chrome pops the menu up. Maps opens the side bar. YouTube pops the menu up. Drive opens the menu.
So it works for some but not for others. Perhaps you could enforce consistency or follow your own guidelines etc.? Go crack the whip.
And I guess they think that the three dot menu is ugly or something.
I'm a new hire, and I've been given the choice of working on one of two teams, neither of which particularly align with my interests.
