Contrary to the other comment, moonlighting is just as easy for someone FT employed to try as someone who is no employed. The FT employed can make 20-30hrs available a week to try out a company on a set amount of work and get a feel for it. The alternative is to go through a set interviews (that if you read the google article, are useless) and then change your job (effectively putting a bullet on your last job) only to find out that you hate your new job and now you are stuck there. Try outs are safer and available for all.

So now we're talking about constricting the flow of candidates down to those who are willing to accept a second job for weeks to mitigate the concerns of future employers.

The problem here is obvious: the best candidates don't ever have to put up with stuff like this. They're actively courted by prospective employers.

Sure, not every candidate can be "one of the best candidates". But why would a rational employer select a screening process that overtly rules those candidates out?
