Why is that? I love take-home assignments. At least, if it's just an initial get-to-know-you interview, and then the assignment. What I utterly despise is the get-to-know-you interview, then a tech interview with the entire dev team, then a take-home, then a meeting with the CTO.
I will never, ever, ever go through with any job that has an interview process like this again. I always ask up-front what their interview process is like.
