So if your name is Lee or Robin or Pat or anything else not clearly male or female, use a Mr. or Ms. prefix. Also, look at some of the volunteer work you've done in the past and see if any of THAT helps document some skills you'll need for your new job. Then list separately each different position you held there, so your job progression within the company is more obvious. ALSO you can just DROP some of the less-important or briefest jobs. But DON'T drop a job, even when it lasted a short time, if that was where you acquired important skills or experience.
Students can make their resume look neater by listing seasonal jobs very simply.
