Thanks Jeff,
I recommend reading two books by Max Eggert on interviews and CVs. They were brilliant, succinct and (lets not deny it) inexpensive.
One of them said there are only really 3 questions in an interview
There are lessons in them for both the interviewer and the interviewee.
Jim is absolutely right. Not everyone is comfortable with "people skills" but at some point you are going to need them.
I would also recommend taking a course on giving presentations. There is a lot to learn in giving presentations that can be applied outside of the presentation arena
