As someone who has had "8 hour" take home projects with requirements like "build a responsive site for this fictitious product and include creative UX features as well as a full summary of thought process during the project" I think this idea is horrible. I refuse to do take home tests, they are a waste of my time.

I've been to 50+ interviews on both sides of the table and can tell you there is always a few questions you can ask to determine someones development competency.

Not to mention I have literally thousands of hours of work I can send you from PSDs to code if you want to dive into my work.
