This. It's important for them to understand their biases. This has a bias towards individuals who either are already contractors, do not have a job, or have large amounts of "free" time that is not dedicated to other endeavors.
Personally, I don't think there is anything wrong with this as long as they understand their bias. Sometimes it's more important to pass on potentially great hires in order to weed out bad hires.
For what it's worth, I would never do this. I'm not going to quit my current job to take this kind of risk. I also don't have "free" time. I have several time consuming hobbies / commitments outside of work that I'm not willing to break for 3-8 weeks.
