"I have never implemented a sorting algorithm from scratch other than perhaps some toy version for educational purposes. I don’t think I have ever implemented something like a heap. I have certainly never implemented a tree balancing algorithm, even though I learned several.".. neither have I... 25 years. The closest I get to that is simply knowing the big Oh difference between a list and a hashmap. However, we keep using algorithmic analysis as a filter for hiring. This is especially hysterical when you're interviewing for a job where all you're doing is writing web services against mysql. Now, I suppose it's possible that I would have combine results from multiple queries in memory in some data structure more advanced than a list.. eh probably not.
