I worked at Google circa 2015, and found the code review process to be actively terrible.
I was writing JS, while my sole teammate was a firmware engineer. He was not willing or able to meaningfully review my code, so I had to try to scrounge random reviewers from other teams. They naturally de-prioritized it, so it took forever. And because they were not involved in my project, they would only have local stylistic feedback.
Months in, I finally figured out that other engineers were just self-reviewing: you can add yourself as a reviewer and just click merge. So I started doing that too.
