It's unusual to have style guides, in particular as extensive as this, except at places that have their act together.[1] Where some sort of style is enforced, though, it's typical to have an automated tool that validates your code. This can happen locally (as a pre-commit hook), remotely when you push a branch (as a CI check), or when merging to master (same). If people are going through and noting style guide violations in a code review, that's generally a bad sign.[2]

[1]: This is my opinion. Anecdotally, places with style guides tend to have better engineering cultures.

[2]: Again, opinion. This tends to indicate a weak culture (dictatorial lead or a lack of awareness/ability when it comes to tools) and can produce a negative atmosphere (nit-picking isn't fun).
