Yup, there are a few on MR who've worked for Apple and posted about it, but when they're hired they have to sign a non-disclosure agreement, so 5 years after they're hired they're not allowed to tell anyone most about the experience, or at least the 'secret' stuff, even if they've only worked for the company for 2 years. There was a thread recently started by a member who hadn't posted in, I think, about 2 years just because he was hired in an Apple Retail Store. He could only post about the basics when he returned, though; from what I understand some Apple employees are hired specifically to check forums like these for people who don't follow the non-disclosure agreement. Many people have been fired as a result of this.
And there are a few members currently not posting on the forums because they're working for Apple as we speak.
About your application, I'm sorry, I can't realy help you
. Maybe you could do a forum-wide search, as there are lots of threads started by people in your position. Anyway, good luck in getting hired
