From this question and others, it seems that it's not totally unheard of for some companies to try to get free work out of job applicants by having them submit projects that would otherwise be done by paid staff. My question is, does a company have any legal right to sell/use that work as if it were done by an employee?
The job applicant has no agreement with the company that would cause their work to be owned by the company. There likely can't be any contract between the applicant and the company to say otherwise, because the company offers no consideration for the application project. If a company sells an applicant's web page to a client, for example, are they violating copyright or otherwise breaking the law?
