the company description would not have anything to do with your jobs. the company description is what kind of place is CVS? I would say “retail pharmaceutical chain.”
ummm, you put what your job title was. Then you detail out your responsibility. If it was a key job to what you are looking for now, detail it greatly. If it is simply a position that you held that has nothing to do with what you are seeking, you don’t need to do into great detail on paper.
