> I dispute that assumption and figure any time outside of that initial hour makes a hiring mistake that much more expensive. Okay, sure - dispute it if you want. It doesn't change the fact that the industry seemingly collectively decided that 1 hour isn't a sufficient amount of time to gauge fit/effectiveness/etc. My point to you is that given the above, you have to make a choice. Spending the extra few hours gives you some hopeful assurance of what you're getting. I once again will note it's not a good system, but there is to date seemingly no widely agreed upon good system.
