One question I remember "what is the first thing you'd do on the job". If the position is technical, the technical interview will be the most important of all. Prepare well. The person interviewing you is a highly experienced expert in the technical area and not a recruiter so prepare and speak from your experience. The person I spoke to didn't seem to mind longer and more elaborate answers. They wanted to be convinced that I did this work before so they asked a lot of "how would you do this and approach that", type of questions.
