Is age an issue?
markkanof: Regarding the detailed questions about APIs, I think that can sometimes indicate an interviewer that hasn't really given much thought to the type of skills that are needed to do the job. I've been guilty of this myself.  Asking quiz type questions that really only test the candidates ability to memorize and don't reveal anything about how they think about problems.As I've grown in my abilities and experience it's become obvious to me that how people solve problems and if they write maintainable code is much more important than if they know some minutia about the development platform.  I've worked with people that could answer all the quiz type questions, but just didn't really have the mental ability to reason about and implement an elegant solution to a complex problem.
