Kevin,
I really appreciate your reply, but I must say that I somewhat disagree with you. The last two jobs I have had I have been asked "logical questions" during the phone interview. These are not supposed to be hard questions but are meant to filter out some of the applicants. In some cases it is not even the correct answer that matters but the train of thoughts leading to the answer that is interesting. A person in this field must know how to use the scientific method. I would not ask code questions over the phone, but generic questions like: What are the main principles of object oriented programming?
A proven track is good, but how do I know that the person has a proven track? By reading a resume? Some people are willing to show their old apps but in a lot of cases old apps belong to his/her current employer or client and how do I know that the interviewee wrote the app (or what parts of the app the interviewee wrote).

>>I will shortly start looking for a new employee (permanent or contract). Does anyone have any good IQ type questions or good interview type questions? If anyone knows of any good websites with this kind of information that would be appreciated also.
>>I like to use some IQ type questions in the phone interview just to find out if it is worth bringing the person in for a face to face interview. Questions does not have to be directly computer related and should be able to be answered within 30 seconds without the use of pen and paper. More difficult questions are also welcome.

>>I am tempted to sneak in a Microsoft question, like : how many cars are there in Los Angeles? Where the object is not to get the correct answer but to use some kind of logic to derive an answer and not just answer I don't know. Has anyone tried that approach?
