I started listing computer parts and using the super technical terms. Pretty sure I said form factor in there. I was being interviewed by someone who knew very little about computers. Just know about computers.and their technical terms. Chances are, you're not getting interviewed by someone who actually knows about computers. They're all getting yelled at by a customer or cursing at driver that failed to install for the 3 time around for no discernible reason. The actual geeks have no time for HR stuff.
