So you require 90 minutes of interviewing followed by a 4+ hour long unpaid homework assignment complete with a presumable additional hour of presenting the homework assignment to a team without them knowing what the pay could be.

I think you'd have to not have many other opportunities to be worth putting up with that much for the potential for a job. Imagine if they interviewed at even one other place that required this much from them, they wouldn't have the time.
