1.) Start general ("I'm an x developer with y years experience.) You want to tell them 2-3 selling points ( I have a lot of experience with x, I'm great at y).

2.) Always be closing. Whatever you decide to tell them, put yourself in their shoes and ask "Does this person sound like a great hire?"

3.) Don't be boring. Your 2-3 selling points should prompt them to ask you more about those things. Don't recite your resume.
