Not sure why there are so many negative comments, the exact detail of the questions and answers aren't as important as the overall message and the guy and girl are archetypes. We're interviewing some candidates for embedded C programming right now and these are the types of questions (although generally easier) I ask to find out the level of C expertise. For embedded systems with a focus on stability I want candidates who have a very good grasp of the fundamentals like the difference between normal globals, statics, volatile, etc. Also I'd like people who understand enough about the linker to know about data segments, zero init and stuff like that. For embedded you generally have to be able to implement interrupt handlers so the exact translation of a line of C code to assembly is important, as is knowing what's atomic and what isn't. I'm continually surprised how many programmers have worked on embedded systems in C without being able to answer almost any of my questions. Many seem exactly like the guy in the examples, none like the girl.
