I've never experienced a monorepo like Googles. How does it work? Are Chrome and Gmail in the same repo? I assume they're built separately and pushing code to one doesn't affect the other.
For GP, note Chrome is a special case because it's an open source-first project so it is not in the same repo as Gmail.
However products are in the same repo such a gmail, youtube, search (frontend, mobile, server, infra, etc), photos, maps, play, translate and literally thousands of other internal and external products and projects.
>How does it work?
Different projects are in different folders instead of different repos.

Yes, building or testing something only builds its dependencies.
