> Recruiters are being regularly ghosted (like they used to do to candidates)
Not sure if this is the same thing (with "ghosted"), but I have 3 rock-bottom criteria before I'll respond to a recruiter's email:
* Send to the email on my resume, not my personal one.
* Show that they've read (or at least keyword-matched) my resume.
* Something in the job description should at least be vaguely enticing, such as a technology I have on my resume. The same thing can hit both points 2 and 3, the depending on how the email is structured.
In nearly 10 years, a grand total of one recruiter got all these points. Half of them failed on the first one.
