> Not because they weren't highly intelligent, but because terms like "bubble sort" meant nothing to them. That's fine, but understand that they often would not be a fit. If the position is low level systems programming for example, not knowing the term "bubble sort" indicates that they will have troubles in getting up to speed in a modern, complex environment, even if they are very smart. Same if the position is e.g. to work on a database, i.e. its actual implementation. Solid knowledge of both abstract and specific aspects of computer science and engineering are prerequisites for a lot of programming jobs, especially where you work on things that consist of the environment itself, instead of the applications that run on it (though this is sometimes true for those, too).
