The most frustrating thing for me is that even though I have my resume planted with approximatley 12 recruitment agencies, I still see jobs on a daily basis on Careerbuilder that are posted by those agencies.  These are jobs that I know I should be interviewing for.  I still however apply (sometimes several times for same job) and then get no response although the same jobs are still posted for weeks. I personally think some of the listings are hooks just for the purpose of recruiting more "inventory" although I have no idea why, since the recruiting companies obviously don't use the "inventory" they have!!
