- I agree. However, I think probably THE most useful question to ask
- might be something like, "Discuss the difference between zero and a nil
- pointer in C. Why does this issue create so much confusion, and what
- is the correct interpretation of 'if (varname)' if varname is a
- pointer to character, integer, array from 0 to 20 of character.

- Face it, you aren't going to find out if they know anything unless
- they have to write an essay. And it's better to do that stuff orally
- anyway, during the interview, so as far as I'm concerned this whole
- 'test their competetence' philosophy is a lose. People who don't
- 'test' well will do poorly, even if they know what they're doing. An
- interviewer can make allowances for things like that by prompting them
- if necessary (and any decent interviewer should be able to tell if the
- problem is nerves or a lack of knowledge).
