I just ask them to talk about the projects they've worked on recently and any issues that arose, and how they dealt with them. If they can communicate clearly what happened. I've never had that fail me as far as them being "technical enough" for the position as no one knows everything, can you figure it out is the bigger issue. Then I typically just have them tell me about what they liked and disliked at prior jobs and what environment they would like to work in. After that, what are their goals for their career and how can we help them achieve them. If the interviewee can demonstrate they have anything in those areas, I've never had an issue with someone I've hired. I don't care if you can program everything walking in the door. If you've got a can-do attitude, we can work together to get you up to speed on our crap code and the whys behind it.
