How is it that a company could not be able to make a decision after 2+ months of a person actually working for them? If it's not a clear "no," we know that person hasn't managed to destroy the company and can at least get along well enough socially. If it's not a "yes" after that much time, that seems like a management failure. After all, 2 months should be more than enough time to produce enough code to tell whether a person can code and will bring a net positive influence to the environment.
