Is this serious? I replied to another person in the thread with a similar take. I agree that large tech companies are not the heavenly place that people depict them to be where everyone is a super genius, but I just don't find what you're saying to be consistent with my experience.
I joined Amazon as a new grad and spent 3 years there. I went from a 0% callback rate on cold applications to like 60%. I've been at Google for 2 years, and I am approaching 80% callback. A third of the time, I get to skip phone screens entirely and go directly onsite.
I don't think that the vibe irl is the same as on HN. I never get the impression that people are weary of Googlers. Maybe my Amazon experience is the difference maker? I think if anything, sometimes I get the impression that the person interviewing me is a bit defensive at the beginning of interviews as they feel me out.
