In general, there are two resume formats job seekers can use when they are composing their own resume: Reverse-chronological and functional formats. There are many resume formats examples for each of them, so you can use them to provide a clear idea of how one is different from the other one.
The reverse-chronological is one of resume formats that are most suitable for job hunters who have similar experiences related to the job they are applying. This is presented by listing the newer experiences to the oldest ones. Functional formats focus more on skills and more appropriate for those with limited or no experiences related to the job applied.
