Overview
You need to be honest and understand what your true limitations are, today -- especially in terms of your job. If you aren't confident about your abilities in a certain area, then the worst possible thing you can do is to say that you are a master of it. That kind of bluster and bravado might seem impressive, but it will only get you into some deep and very hot water. Be honest and be humble -- the people who have authority over you will appreciate and respect it.
