I'm with him up until "never be interested...", thats a piss poor attitude. I've never needed to know big-o complexities for work, and I've only scraped the surface of needing/using various data structures, so I get annoyed at some of the heap/tree trivia questions as well. But if I were in a situation at work where I needed a tree, of course I'd stop coding and read up on how binary trees work and use them for my benefit.
