For my part, I had a couple of decent shots at getting a tenure-track job, but I doubt I'd make it through more than a couple of rounds of Google's interview process. Perhaps it's easier than I think though (I've not tried it), but for sure there are vastly more people who want to work at Google than there are positions available.
The chance of getting a tenure track job can vary a lot from field to field, so it's not surprising that people are reporting very different views on this.
Getting a job at Google is "just" a matter of graduating from a good school, grinding 500+ leetcode problems, applying at the right time, and being somewhat lucky. I would say that anyone who managed to get a tenure-track job is able to do this (provided they are willing to spend the time preparing for the interviews - which is quite a commitment).
Getting an academic position is harder. Even though I've seen very average people getting one too...
