I have learned programming on the job, not in school. I think I have a pretty good handle on things like recursion or traversing or implementing structures. But I don't speak the lingo so I don't know what "Implement a recursive depth first traversal of a tree" means exactly. I have been doing this for 25 years now and I don't think I have ever heard anybody formulating a problem that way.

What do you mean, you don't understand "lingo"? Do you not understand english? Because that's an easily understood english sentence, and you just claimed "pretty good handle on things like recursion or traversing or implementing structures".

What's the difficulty with questions like that? But honestly you are lucky if you get asked these questions. Usually it is more about some absurd dynamic programming questions.
