Fair enough. If the position is actually relevant (i.e. not obviously scattershot spam--which I do generally just ignore), I'll at least politely decline. And I have had a couple followup phone calls but there wasn't really mutual interest for various reasons.

But, TBH, I'm far enough along in my career in this point and have a sufficiently specialized role (my current job had the description written for me after I started talking to the company) that random recruiting is unlikely to be a fit.
