Another tip that I wanted to share (ya'll can tell me to sit down at some point).. be able to provide specific examples and be able to speak about these examples at length. This is very similar to the suggestion of using action oriented phrases for when you craft your resume. For example, rather than just saying "I am a hard worker, I'm a diligent proof reader, etc.." be able to support these statements with concrete examples. Give an example of you putting in tough work and seeing a project, rather multiple projects through, give a detailed answer on how you proof read. When you are practicing your interview answers (and you should practice, just don't give canned responses "... and people love me!" ) carry on a conversation with yourself about this particular example. A good time to do this is while your driving - and yes at first you might feel goofy. But what it will do for you in the long run is help you to speak comfortably about this example without your nervousness getting in the way of providing a great answer or additional fodder for a tangent that the interviewer starts on this subject. Think about the type of question you might be asked and start answering it in a conversation format -- like you're speaking with the parents of your BF (assuming a casual but respectful tone and you want to impress them a little without being arrogant). Get the basics of your response in a format that you can remember, say three elements, but also, let your mind wander about some of the wider implications of your answer. You're bound to get some additional elements in your mind that you can discuss if the interviewer starts a long rambling tangent/conversation about your answer.
ok, my baby is pulling on power cords, gotta go!
