When job hunting you should always be yourself and no one else. This is part of how you set yourself apart from the competition out there. You need to do your best to differentiate yourself from anyone else. While there are limits to what is acceptable, if you're different you'll be the one noticed. Your resume will come to the top of the proverbial stack. This is precisely what you want, to stand out from everyone else. Your personality, the way you write, your body language are all part of what I would call your package. This is your advertisement to an employer, it's what they see.
Let's go a little further into the concept of a package. When you go into a store take a look at the boxes, the packaging that an item comes in. There are many parts to that package, there is the way it looks and the way it communicates. As a rule it will tell you what benefits that the item will bring you though it won't usually directly state that, you infer it in your mind. This is also something that an employer does when they look at your resume. They infer what the benefits are that you are bringing the organization.
