Agree. I'm talking about the US. Much like today where the belief that 100% of the companies do leetcode, 20 years ago the belief was that 100% of the companies did brain teasers.
Neither are true. And that was my real point. There was still the annoying cargo culled crap that way too mnay companies used, but back then, just like today, plenty of companies don't do this. And that's your point.
EDIT: Don't get me wrong. It's annoying as fuck how many companies interview this way. It's just not as ubiquitous as HN leads on
