countdown to communications

I'm gearing up/fearing up for my interview friday with the king of assurance. Is there something I don't get about comms? it all seems pretty fundamental to me.
I was wondering, though, if i have to learn to talk in california sing song if i want to really sound comms-y. That appears to be one of the things you learn in comms school, or at least that's what i hear from every person who tells me they work in said "area."
