>>The interviewer was one of those typical impossible to please/thinks he is smarter than everyone, long haired programmer guys. >>The questions were impossibly difficult without prior exposure >>I couldn't answer many of the coding questions during this interview because they were focused on specific algorithms that no amount of preparation would be enough These questions are just becoming very common these days. There are thousands of programmers spending hours every day on online judge sites, and other associated competitive programming contests scattered over the internets. As these things increase there is growing question bank of impossible to answer interview questions. It also turns out most people who hop jobs often are the same people putting in these efforts into competitive programming contests, and these people justify their investments in time to ask these questions and to keep it as an edge over others. The questions are just impossible to answer unless you spend hours every day on these competitive programming sites for years. It also turns out these people move companies in an year always. If your greatest skill is interviewing, working for one company for years seems like a waste of your skills.
