Apple Sr Software Engineer interview questions

Technical phone screen. Question on hashing, Java fundamentals. Was a bit taken a back I was 100% CLEAR before the interview I hadn't done Java in 10 years, and was said that would be fine. Yet the interviewer asked very specific Java question, even to the point of being silly (what does finalize do)....What was interesting is I answered them all, and all questions correctly. But was told the next day by HR I wasn't a fit. Which was weird. All the questions were technically which I answered correctly.
