When looking for a job, the first goal is to grab the attention of the recruiter with your resume. A disorganized resume that is difficult to read will put you at the bottom of the call list or eliminated depending on the total number of applicants there are for the job and the number of positions they are looking to fill. Your jobs should be listed "newest first". When I get into a crunch, I pull resumes rejected for significant "work history gaps". 9 out of 10 resumes I look at who had been coded for "no job in last 5+ years" has their resume formatted wrong and the computer picked up the first job listed on the PDF or word document.

When writing a resume, you need to be self aware of what you did and how you contributed to the company. I just saw a resume where the person worked at a large food store warehouse (and they spelled the name of the employer wrong). According to the resume the only thing this applicant did for the company was "make lots of salads".

You should take the job you did and figure out the steps. For example, order receiving to determine workload (what salads I am making that day). picking ingredients from pick slips (recipe cards, etc.) Measurement and assembly. Staging product for display (consider salads in the case at the deli), etc. Maybe you found a faster way to get the job done by doing the tasks in a certain order. This is a contribution you should list.
