Imagine I'm an employer who wants to adopt this system. How can I distinguish the candidate who spent four hours from the candidate who spent twelve?

If you care, you enforce a time limit or have the work sample done on site. We simply don't care.

Thanks for clearing that up. So if you employ someone who's actually really slow then I guess you just fire them?

I'm based in the UK, where firing people is harder, so this wouldn't fly. That said, I know interviews are basically useless so I would like something better.

I have no idea. It's never happened.
