Most of the technical and problem-solving questions on the quiz they gave me were fairly straightforward, it's the verbal interview part I'm not quite as confident with. They wanted me to edit a file (by means of hand-correcting a printout) that I'd never seen before, and apparently I got it nearly right just by making educated guesses. I also correctly solved a lateral thinking problem that they say few people do.
Surely someone out there needs an antisocial, introverted logical thinker to just solve problems all day in isolation?
