Interviewers especially at the startup (where they think they would money by selling product) ask the questions like we developers need to use them daily by hand. These freaky people do not understand there is a difference between a DEVELOPER n a Dijkstra kind of developer. If I am a Dijkstra kind of developer i won't be working at your startup for some peanuts (either I will be at google/mfst or some other big company). Its not like you shouldn't know it there isn't any use of this. Illustrate a simple example through your career (<1% of all developers) where you have to innovate a SORTING/SEARCHING algo. This works happens in PHD where your sole goal/aim is to find/do something. So interviewers rather then asking this bogus questions ask architectural questions, framework questions, coding things because this is what makes your product. For Sorting/Searching you will always use a library. Believe me, I hate being asked such questions during interview which can be found in a book. So please interviewers do ask relevant questions, we are there to develop your product not algo otherwise, if we are so talented, that definitely we wont' work for you.. :)
