Love this! Was in a coding interview once where they just gave you a problem and you were given laptop and time to code out a solution using whatever you would normally use ie stack overflow. First interview I've had where I felt like it was a fair test of my programming capabilities.

Of course this requires that you design the question in a way that is not completely google-able, but real world programming is not just about solving a trick question but being able to be resourceful enough to find a real working solution.
