People are actually not outright hostile to a call from someone who wants to talk to them about a job.
I never got that: YOU put your resume online, indicating that you would be interested in considering a new role. Why are you mad that I am calling you about one?
Even if the role I call you about is a little different than what you are looking for, a) isn't it nice to know you have options and b) seriously what the hell is your problem?
"No, thank you, but I appreciate the call." Eight words, probably what, three seconds? Lord love a duck, unless you just got the diagnosis and you only have four seconds to live, chill out already.
Anyway. So that was the world I used to live in when I was last recruiting like this. It seems to be a whole different ballgame and I, for one, am not complaining at all.
