Is this something unique to the personalities of people that thrive at sales jobs? I've encountered this sort of behavior with real estate agents, car salesmen*, and of course, third party headhunter/recruiters. They love phone calls, will try to get you on the phone no matter what, and actively try to avoid e-mails/text/etc.
* although, I recently purchased a car a few weeks ago, and nearly all my communication with the salesman was done via e-mail and text. Very pleasant experience, but I wonder if this is the new norm, or if he was a unique exception.
