Job Hunt Question: Does recruiters interview just for the heck of it?

I'm really curious... Is there a policy for HR or nurse recruiters to have a minimum quota for people they have to consider/ interview for a position? I've gone on a couple of interviews, four of which are for major hospitals in my area. Although I'm pretty sure it's me that has the problem (being beyond dreadful with interviews), I've recently read an old thread on how HR/ nurse recruiters have to interview all applicants in the running despite having made up their minds.

Do they do that?

Would HR/ nurse recruiters call applicants for an interview just to "fill in" /pad the number of applicants for a position and make it seem more in demand, in paper (or in their records)?

In online applications, why would they "apply" you for jobs you haven't personally chosen to apply for if not to pad their applicants-for-consideration numbers? For example, in your "jobs applied basket" you might one day find a number of positions you haven't personally "applied" for. (Happened to me. And I know every single job I applied for!)... This bothers me. Isn't this falsifying records?

Any thoughts/ info on this is greatly appreciated!
