Which questions are most successful at gauging the UX design experience in a candidate? What approaches are best used during a job interview for a UX design position?
First: Hello. Welcome. Thank you for coming to see us today. Take a seat. Coffee. Put interviewee at ease.
Then: "Tell me about the experience you had getting here today."
It has no correct answer since the interviewer knows nothing about the journey. But the interviewee actually undertook the complete experience so should be very much in a comfort zone.
It's great for seeing what was noticed, how it is communicated to someone who wasn't there, and of course it's very much a case of seeing if they pick up on what you are expecting of them and can convey the experience descriptively and passionately ( or not...) and if they can actually 'tell a story' in the process.
It's such a lovely little big question.
If you had the power to change one object/device/software application you use regularly, what would it be? How would you change it?
I would then listen for answers to the 2 questions I didn't ask "why change it?" and "what will the implications be?" Everyone can come up with ideas but few people can explain them well and see the bigger picture.
One thing we always do is a design exercise that is abstracted away from the specifics our application. It tests the creativity and interaction design talents of the applicant. There are half a dozen different answers, and any are good, we just want to see thought process.
The specifics of the test have to do with taking something with alot of values and binning them into groups.
Ask very open ended questions, as indicated in the other answers, to see if the person can explain and explore their world and their experience well, and communicate it to you.
Ask them slightly more focussed questions on what they like to see and don't like to see on sites and why. Make sure you are verifying their REASONING not their CHOICES.
Test them in an exercise, and be sure that their processes, not their results, are what you are looking at.
Quiz them on how they will deal with recalitrant developers, pushy managers, incompetent co-workers and over-optimistic sales people.

OH. I came across a great doc on Slideshare yesterday. It has common questions, UX/UI specific questions, and questions that were asked by Fortune companies.
