While I agree that you shouldn't sell yourself short, I think it is also interesting that somone is taking the first step in letting their potential employer validate a potential employee's potential (too much potential there). Also, it lets the employee validate the quality of the work. I think it;s okay if done for a couple weeks (short project/assignment). If the employer likes him, he/she can pay him for the work done - out of goodwill. Everyone wins (only in a perfect world).
