I think in many cases "random hoops" are useful in interviews - they show that you can modify your solution to accomodate unforeseen problems, and make sure you know the full scope of the problem (by asking questions about it) before jumping in with a solution.

If the actual job involved solving random problems in an instant, then these tests would make sense. As they are, they're really just statements of power: I have a job, you want a job, so I can make you jump through this hoop. I am great! Look at my little fiefdom.
