Obviously taken into account - I still have no problem whatsoever identifying great developers on GitHub and I'm sure many other developers who actually code often could too. You have bigger problems if you can't tell if someone is lying or not about their abilities when all their work is visible to you. You should be able to easily tell what is theirs vs not.

Yes people inflate their own egos and abilities - especially those who spend all their time interviewing others instead of building.
I prefer demonstrable experience for an engineer over standardized tests which tell you nothing about any real world experience: App architecture, async programming, APIs, UI, DOM, git, unit/e2e tests, any known framework or library, etc. A person who knows all those but hasn't memorized CTCI is a lot more useful than the CTCI memorizer with no evidence of work ever performed.
