I don't dislike coding interviews either. But if I were asked about a Convex Hull, my response would have to be, "What is a convex hull?" otherwise I'd have to guess. I have a computer science degree, did I miss something? Is that common knowledge? Right now I have the power to look it up, but it's a little strange to me that I could be asked about that in an interview and my pass/fail would potentially depend on it (granted when I am the interviewer, my pass/fail rarely depends on the response to the coding questions).

So the next question is, will interviewers explain the problem if you're unfamiliar and not "fail" you if you can explain how you'd approach a solution?
