I was chatting with one of the admin folks today, one who has spent some time lately making happy phone calls inviting search candidates to interviews. And here's hir advice:
1) If you don't already have a professional email address, set one up. Don't use hotsexnowATproviderDOTcom.
2) If you've been applying for jobs, and you're hoping for phone calls, answer your phone like a professional. Say, something along the line of "Hello, Mary Smith speaking." Yes, it feels awkward at first, but it's way better than "Yo yo yo!" or something, at least according to this admin person.
And that's it from the happy admin side.
