Doing the technical side of an interview

I remember the first time I did an English test for job vacancy in a big corporation. There were a written exam and an oral exam.

The written exam was a test model with just 40 questions that went from easy questions to very complex questions. The difficulty of the questions increase and increase till question #40 that was related to English literature words that belonged to the ancient times.

For the interviews, I call the expert that will do the technical interview and ask him this process and build with him a list of ten questions that goes from the easy ones to complex ones.

I look for the way the person replies, how honest is the person when I ask something he does not know, how the technical answer is described in detail or if it is just beating about the bush.
