I disagree. I know I might get shit for it from HN, but I don't remember jack shit about specifics of implementing sorting algorithms or how to invert a binary tree, because I don't need it right now. I know some of the ideas about why and when you need some sorts over others, but the ins and outs I can get if or when I need them. Currently I could talk you damn ear off about 9 different ways of doing a topological sort (and which ones you can use if it's guaranteed to be a DAG, etc...), but that's only because I spent my last few days working very closely with stuff like that. Ask me in a month and I'll be back to knowing jack shit about the specifics. I'm terrible at these kinds of interview questions, but I feel I'm a productive developer.
