One of my last jobs was working for for a sub of a big health care company as a sr. unix admin / security admin. I had an interview with the CIO set for Tuesday at 4:00pm. I called the CIO on the Friday before and told him I was Mike Hammer with EDS, and that the corprate CIO had asked us to finish the security audit we had started erlier in the year. I got a meeting set up with him at 2:30pm on Tuesday to go over the questions. I showed up at 2:30 and proceded to gleen info about his systems and network (firewall type/os/verions, os types and versions used, externally exposed boxen, fireweall rules). I walked out of his office at 3:30 and went back to the receptoinist area and waited for my 4:00pm interview. The look on his face was priceless.=)
