I agree with Jeff on the need for the technical questions.
I remember seeing a resume for a DBA that seemed to have good experience. I was eavesdropping on the phone interview with this person. From the way he answered the technical questions, which were all based on his resume or a previous answer, it was obvious that most of the items on his resume probably referred to projects where he was a member of the team that did whatever, but he was not the person who did it.
Without asking the technical questions, we would not have known he knew much less than he was implying.
