Absolutely none? I somehow doubt that, otherwise only the most incompetently run companies would still ask for that kind of commitment during the process and... Actually, you might have a point. I certainly have rarely liked work in companies that demanded free work from me during the hiring process. That might be one of the reasons why I haven't done an unpaid take home test in a long time.

> But the idea that the company is getting you to do work for its value outside of the interview process just seems

So the company isn't getting the candidate to work for free because it isn't getting value... If we ignore the value it gets from the interview process itself.

Providing some company a service so that it can make a decision on how it operates sounds like work to me.

On another note, this doesn't take into account that pointless busywork is still work.
