Reverse chronology is the easiest method to use. It is also the least effective because it makes when you did something more important than what you can do. It is an especially poor format if you have gaps in your work history, if the job you seek is very different from the job you currently hold, or if you are just entering the job market. About the only time you would want to use such a resume is when you have progressed up a clearly defined career ladder and want to move up a rung.
