The company rates you post-interview, and one of the things they rate you on is how seriously you took the interview. So, basically, they can't weed out people just doing it for the money, as long as the person takes the interview seriously and acts professionally. Regardless, I think this is a good idea, it will definitely work as a self-funded company.
This sounds like a good idea. I wonder how they decide if you get the money or not? I.e., how do you weed out people just doing this for the money?
