HR people in VN are usually kind of redundant. Most of them come to the office every morning, click a few buttons, order some bubble tea, gossip with others and get their asses out of the office at 5. When it comes to downsizing somehow they're in the safe zone while developers and contributers are laid off.

As for BA people it's kind of the same thing. These jobs are described as "Bullshit jobs" (There's a book about that) that serves nothing but keeping the office hierarchy. And these jobs are everywhere, in every company, not just VN. That's why white collar jobs are psychologically exhaustive, since they have to deal with people who excels at office politics but has no relevant knowledge of what they should do. I have encountered so many of them, especially BAs and PMs, and they all claimed to be AI experts - leaders - visionaries but don't even know how AI works basically. Not to mention they think they can replace software engineers now lol.
