Unity tripled in size in like 4 years iirc. It is trying very hard to be a large company. Like the culture has been shifting from small company feel to big corporate feel for a while now (since before I joined). It still is clinging very hard to having small company feel though because that's the kind of culture almost everyone here was sold on.

As far as the efficiency of our size, I'm honestly not super sure. We've been multitasking a lot and have cut things in the past, like Gigaya. My department has always felt understaffed and I get the vibe that a lot of departments feel the same. I haven't talked to anyone that was like "my team is too big to function well". So if there is an inefficiency issue it is maybe a broad thing that could be hard to see from any one part of the whole. That said I work in a very specific part of the company and don't branch out a whole lot to other groups so my interdepartmental knowledge is limited.
