For me, I think that unpaid homework is an acceptable, if not important, part of an interview. However, it must pass some qualifications: * It can't be taken as real work at all. Something like building a game is clearly not "real" for a SaaS company and still conveys lots of value * It should be discussed in person as the in-person technical interview (don't come in an whiteboard in addition to the outside work) * It is provided only after a phone screen and it is discussed on the screen. * There are clear objectives and "bonuses" * The language of choice can be used With this, I think that it provides value to the interview process and helps the interviewee as well by simplifying the in-person technical components of the interview.
