Chromium is a massive project. In more normally-sized projects, you can build everything on your laptop in reasonable time.

When I worked at Chromium there were two major mitigations:

1. Debug compilation was split in shared libraries so only a couple of them has to be rebuilt in your regular dev workflow. 2. They had some magical distributed build that "just worked" for me. I never had to dive into the details.

I was working on DevTools so in many cases my changes would touch both browser and renderer. Unit testing was helpful.
