If practice didn't work - how come every professional performer practices regularly? Quite simply it is because performers: sports stars, musicians don't have the time to think about how to perform - it has to be "muscle memory". In an interview, a candidate needs to have the muscle memory to do the work in a timed manner. I have had candidates say they know Java and then not demonstrate their knowledge. (They might indeed know Java well - but have been out of practice!) I suspect the OP is a very smart person, who can "muscle" his way through most interviews. Most developers are mere mortals and can not pull it off. This is the danger of listening to exceptional people - their techniques do not apply. ---- As for preparing the candidates by letting them know the questions, as an interviewer, I want to judge the candidates based on their best performance. At my company we have a very practical approach to interviewing - it starts with no brainteasers. And yes we are hiring for all levels! (reply if in the bay area)
