I think we have this post every few months on this site, so let me explain how recruiting works.
There's 3 types/market for recruiters and they almost never overlap.
The first are "body shop style" recruiters. It's basically a numbers game where they try to cold-call as much people with githubs/linkedin or blogs that reference programming. They don't know programming (not even what's the difference between languages or front-end/back-end) and are looking for a list of buzzwords. They'll send copy-pasted messages (you can tell because it references tech you never used or never even claimed to have used). If you respond (and really you shouldn't) you won't be able to get any relevant information about the position because... they don't have it. These recruiters are often contracted by external firms in "best value countries" and are given canned response to message you. That's probably what the author encountered.
Second type are professional recruiters. Their salary is by commissions will often be a percentage of your salary. They are knowledgeable about programming and tech (often former engineers who wanted a break from coding!). They typically are looking to match specific profiles to specific jobs at client companies. This goes all the way to recruiters specialized in C-Suite executives (and you can picture the commission finding a CEO will bring in). Their messages will be personalized and you shouldn't hesitate to reply back even if you aren't looking for a job. They know that most great software engineers are almost never openly looking for a job so their goal is to be on good terms with a large number of talented developers so that the minute they start looking for a job they can match them with positions. You'll know when you encounter one.
Third type is basically referrals. A players attract A players, smart companies know it. Make sure your referral bonus is a percentage of total comp. It's probably the most effective way of recruiting (it has an insane signal to noise ratio). But you only get access to that type of network by... bringing value and being part of it in the first place!
My point was more that even Google -- a company with a 1.9 trillion dollar market cap -- is now relying on cut-and-paste-error recruiters, even when sourcing for roles which pay $500k+.
I've seen a lot of cringey recruitment communications over the years, but rarely encountered it for very senior roles at top companies in the past. Seems way more common now.
