Google places a pretty high emphasis on code quality and readability. It's not universally great, but it's a big part of the culture. You can catch a glimpse in their [style guides][1], [abseil totws][2] and [aips][3]. Almost every change is required to be reviewed for "readability" in addition to functionality. This can feel like a lot, but it leads to pretty consistent style across the codebase which makes it a lot easier to switch projects or read and understand an unfamiliar section of the code.
