Interviewing people

Every now and then I get to interview people. My interviews are based on a FreeMind diagram that acts kind of like a meta script.

I believe this kind of interview can give me a pretty good idea of the candidate's skills and attitude, but is probably not deep enough from the technical point of view.

I've found a site that can help me here. Well the purpose of the site seems to be helping candidates getting a great interview, but it still is a great resource for technical questions. The site is FEDIA.NET, and stands for Free EDucational Interview Answers on the NET.
