You should really read your own link - the part where he admits he made that whole story up. Im gonna guess failing some basic coding is not what tanked him. He still thinks they owe him the job though because he’s kinda famous and did a popular project in a language that Google doesn’t use, so that’s cute.
I also dont see how this one anecdote (even if it was true) invalidates anything I said above. You’re gonna have false negatives in any system you chose unless you just wave everyone in
