It's a test of the candidate's willingness to repeat something they have done in order to accommodate either a system glitch or colleague's mistake/oversight.

It's a test of the candidate's willingness to repeat something they have done in order to accommodate either a system glitch or colleague's mistake/oversight. I have worked with people who would sincerely reply that they already submitted the resume, and others that might take it as a personal insult that their resume was 'lost'. This filters out those types of people, as well as those that aren't very interested in getting hired for the position.
