Law School Toolbox interview questions

As part of "the process," I was asked to provide feedback on a "sample essay." I was told to return it within a week, but before the week was up, my interviewer emailed, asking "where are you" on the project. I returned the feedback within 24 hours and was promptly informed that they would not be moving forward with "the process." Now, I am overqualified to tutor for them, having nearly 20 years experience as a law professor. I provided excellent feedback on their "sample." It appears that they have a hustle going whereby interviewees do the company's work for free. I would stay away from these people.
