Could not have said that better myself. Most recruiters seem to gloss over half the resume. I have had offers from the medical field b/c one simple key word was in my resume and the recruiter marked me as a possible candidate and yet I have never ever held a job in the medical field. I usually use one or two bullets describing what I did at the job and then one or two bullets (usually one) describing something I improved upon or innovated while at the company. That says a lot more than simply what you did while on the job and it shows initiative. Often I feel like 3 bullets is the max for each job and while it feels like you are not completely describing the job it is sufficient for the resume. The rest can be discussed in an interview.
Recruiters rarely read all your resume (and understand only parts of what they do read...)
