Many times I've had to submit names and background employment history to clients in final stages of closing. The functional resumes only contain the home city and project history relevant to the job at hand. I and many co-workers have six or seven different versions. We don't require any security clearance, but most have had in the past and subsequent employment contracts require it. In the past some seeking a particular job would cherry pick from different sources but it usually spelled trouble. My co-workers also don't go outside our group and some have even been instrumental in landing some important jobs as they did the selling before the salesforce even knew about it.
