There were not really any difficult questions during the interview. They were all questions, that if you thought about them seriously, and pulled from your own experiences, you would be able to answer well. Either that, or you should be a really great storyteller, able to pull details out of your butt. The worst part of the whole thing, for me, was the weird data entry test. I had never taken a data entry test like that before. It was formatted oddly, on paper, and though the instructions were clear, I did not seem to be able to program my fingers to obey instantaneously. I passed with the most allowable amount of errors, at 11%. I asked to take it again, but was told "The most important thing is that you passed. No, you may not take it again."
