Asking too interesting questions can go the wrong way too... I interviewed for very successful startup. They decided to throw some "real world" problems at me-- problems they'd been struggling with for a year. The interviewer spoke very poor English and could not describe the topology of their systems but still managed to shoot down every idea I had. Not sure how I was supposed to solve a problem in 45 mins that had been haunting them for a year.
