On 1/23 VectorMonkey created a post called "I'd Rather Die." Nice post about the fear of public speaking which terrifies many a person.
While a job interview doesn't technically qualify as public speaking, it is rather public, and it can certainly be likened to a "presentation."
If you've got a pending job interview, this post will take you about 30 seconds to read, but I think you'll find a gem that will help you prepare for the interview.
Hint: it has something to do with your "voice."
