We’ve turned into a Hive, things are getting serious.

I can't say I've seen much in life, but I haven't encountered anything in the IT industry like, for example, "a recruiter checks a candidate's social media profile, how many friends and photos they have" or "selection based on zodiac sign." More often, the opposite happens – they don't filter properly, sending out applications from 2010 or with a clear mismatch with the basic requirements. To be fair, I've also seen good recruiters.
But... again, I won't argue, the typical situation might be different. This is just my experience.

I also know at least one HR person who is very selective when it comes to hiring IT specialists. Moreover, she has been headhunted by various companies, but in reality, this person works herself to the bone because of this honest approach and has been thinking about changing her profession for more than a year because good HR people burn out very quickly.

Well, yes, but this is true for specialists at a higher level. And we were just talking about junior developers who "undercut" prices. And people who can't sell themselves because they send out a lot of applications for very little money. And the employer sets a low rate.

But junior developers also negotiate and put on a show. And in some cases, if a candidate has successfully passed the interview and they see unreal potential in him (even if he is actually just talking nonsense), they may agree to his terms. But this is only if he has charmed them. Unfortunately, I know such an example personally (not from IT), when a person told a lot of lies about how he is an excellent technical specialist, repairs PCs, laptops, tablets, and smartphones, and solders like a god. They hired him with open arms, agreed to give him a higher salary, and then he spilled glue on the GPS navigator's board during the repair and told the client that it was impossible to fix this wreck.

I would take a simpler approach to this and even see it positively, even if they clearly ignored your requirements.
In general, this means that your application was good. And that there are not "HR bots" on the other side, but people who care about the result. It is also difficult for them to find a good employee; it is a rare commodity. So you are good, they tried to offer you something, and an attempt is not a torture.

And I think that in the case of Kosha's example, the HR person simply doesn't care. One of the standard questions in any interview is why you decided to change jobs. And if Kosha was asked this, and she made it clear that she wants to change direction, and not just that her previous employer was bad, then offering her an uninteresting vacancy later is inappropriate.
