This is one of those "wow, so perfectly obvious no one has never done it." This could (and probably should) the hiring process at many retail and service jobs. In my teens I would have been all about proving myself by taking whatever quiz or prescreening training available to get the job. This could have micro impacts on allowing the most tenacious to get the job rather than the most experience, which for the level of jobs they're focusing on initially could be a positive force. Just imagine if Wal-Mart was filled with the most proactive, not just the one with 6 months more of register experience. Certainly many caveats to these statements, but with some evolution and execution this could have really important impacts on the way low-level wage employment is conducted. The interesting aspects would be to see it move up the org chart. Also love the customer development of them walking the unemployment lines to understand the market.
