Eh, I could complain about it at length if you get me started but the root cause is they have a process where you have to take all your ideas before a committee of senior engineers and get permission to do anything, and the people who are on the committee are unfortunately not qualified for that purpose, they just happened to have been early employees who blundered into fancy job titles. Aside from that there's also a special clique who do whatever they want to do without regard to that process and the existence of the clique is incredibly corrosive to morale within engineering.

Coming from Google, where you definitely do not need to bow and scrape before Jeff and Sanjay, and even if you did they are both gods who are more than qualified to comment on your ideas, the Dropbox system was a big shock.
