Interviewed at Samsung ( Noida India) around 2016, where exactly the same thing happened with me.
Was being interviewed by a panel of 4-5 people. The main guy, who I presume was the hiring manager stood up in the middle of the interview and left the room, seemingly unimpressed with my answers.
Thankfully I didn't get through and heard many horror stories regarding their culture in later years.
I feel that people who find HN good, do so for a reason.
They are the kind of people who are in majority in HN. They have similar views and when they comment here on HN their views are accepted and prompted more readily.
This makes it a kind of an echo chamber.
All deviants get banned or their comments are greyed out.
Dissenting is not allowed and dealt with severity and finality.
Being an Indian, I can vouch for the fact that this is a South Asian accent, and very high probability that it is from either North, West or Central India.
I don't know why these young people have got into this. There's plenty of opportunity to get a job in India today, if you can even read and write just a bit of English.
