Many years ago I interviewed a guy for a PC support job and he brought all these certificates that showed he was certified to work on various pieces of equipment. Most of it was old, even 15 years ago. For instance he was certified to work on Epson MX-80 dot matrix printers. The really weird thing was they were all in frames with glass and everything. No, I didn’t hire him.
OMG... I think I interviewed the same guy once. I didn't hire him either. :-)
