We do interviews in person where I ask a few basic questions and listen for the answer, then assign a somewhat complex problem to be solved in a pre-prepared iOS project. Google fully allowed. I'm not even looking for a 100% functional solution or even particularly elegant code, I want to see how a candidate reacts to pressure and how resourceful they are.

I would say the majority of our hires don't complete it and I always explain that's fine, the point is to observe the process they used to create whatever they created.
