On interviews, I had a great deal of success hiring for clerical assistant positions by simply getting the interviewees to do a simple problem in front of us. It turned out to be a great, reliable and easy-to-justify sorter of candidates.

But, of course, it was neither unstructured nor much of an "interview" as such.
