The question is, "How do we determine if the candidate's definition of work matches the employer's definition of work?"

Well, the candidate would be giving away a week of his time, which can be a bit problematic. How would you arrange this if the candiate was already employed?

He'd take a week of unpaid vacation from his current workplace, and give it away on a chance he might want to switch jobs and be accepted? Besides, 1/4 of your monthly salary is definitely a noticeable loss.

What if this was a common practise? "Oh well, this didn't work out. I'll take another week of unpaid vacation to try out for that other company then"..

A lot of people think of work as "sitting in a cube."

Working for some place means exchanging your time for money. Whether that time is spent coding with a burning passion, moving a company in a desired direction, or looking at lolcats is another matter.
