It wasn't snarky at all. You are being overly defensive for no reason.
I've never been asked to "grind" leetcode, I've never been asked a leetcode style question at any interview I've had (and I'm in my mid 40s). I've never had any feeling of needing to do leetcode, and as far as I know neither have my friends.
The reason I asked if it was mainly a US thing was because I assume (maybe wrongly) that the majority of HN users are in the US, and this leetcode thing pops up a lot.
