George made that name up on the spot in haste. He extends the lie further and says that he was interviewed by a person named Art Vandelay. (Again, a made up name.)
George is seen using the name "Art Vandelay" in many other episodes whenever he is in need of a fake name. Interestingly enough, in "The Finale", the judge's name was Arthur Vandelay.
What was the inspiration (if at all) for the names "Vandelay Industries" and "Art Vandelay"? Did the show creators/writers ever comment on that?
Update: The reason I am particularly interested in this name is that Google tells me it is not a common name at all and there is no real life company on which the name might particularly be based on. Sometimes such peculiar names are inspired from on a real life company or names and then modified and conveniently mocked.
(And oh this: Art Vandelay on Linkedin. I am amazed!)
