This is good advice, but needs to be tempered with common sense :)

I once interviewed a person who was so enthusiastic that after the answer to the first question was not finished after 10 minutes of babbling, I had to cut them off, and this continued (with shorter intervals, I do learn :) after every question. Normally I have the opposite problem, people don't give enough information, this person was so excited...well there was no way I could ever imagine working with someone like that on a Monday morning :)

"Nothing is sure but death and taxes" I say combine the two and its death to all taxes!
