I'm really not sure whether this belongs in General Programming or Job advice, but I'll try here...
Looking at some of the jobs out there, twice I've been asked on a phone interview to rate my C++ ability "on a scale of 1 to 10". I've had great difficulty answering that question. C++ is a huge language, and a "10" can be anywhere from "mastery of template meta-programming" to "practically sits on the standards committee". Obviously no two peoples' metrics are going to be the same, but does anyone have an idea of what those scores typically shoot for?
