In my opinion, these home assignments are not the way to go. Split tasks into things you want to evaluate; giving a giant assignment and expecting to evaluate every single competency from it is disrespectful of a candidate's time.
Also, if for some reason you really want to do a home assignment, do the candidate a favor and spend a minimum of one hour giving thorough feedback. All I got was: Nothing. They didn't even bother to send a feedback email, which is super disrespectful.
