Be courteous and above all, truthful. You don't tell a snarling bull where to strike next. You stand proud and rely on your training to prove your mettle. Lying about anything ends up evaporating into useless dust.
My advice to a "newbie" is NOT to fool around with trying to "fool around" with employing and interviewing personnel - this is their business! They have to be fast and accurate. So be honest and describe your past experience accurately. If you stretch the truth in an attempt to make your past more appealing, the fake persona will show itself clearly eventually.
Be professional but open as many of the jobs require personality and innovation but you have to let them know you will represent the company well. Remember you are interviewing for assignments but they are trusting you as an ambassador of the company.
