I'm a little late to the party, but just to help everyone with timelines and all that, here is my history with the AHA position if anyone was stressing about a timeframe.
Applied online on 08/20, received a call from a recruiter on 08/22, the recruiter stated in this call that the position would begin in November. Scheduled my first Skype interview (Skype is OK! Don't worry if you don't have a way to FaceTime) for 8/29. Scheduled my second Skype interview for 08/31.
Was offered the job on 9/09. My BGC says "Complete: Meets Company Standards" as of 09/14 (Log in using the same link they provided for you to give them the info to run the BGC, you can check and view your BGC there. If you want the exact percentage of completion you must call HireRight). I have not received a post-BGC call from Apple, however.
So I think it really depends on when they plan on doing their hiring. Apple most likely opens their requisition for applicants WAY before they intend to interview. I suspect during this time they are weeding out candidates using the provided applicant information. I think I applied right at the end of this period and got lucky with my time frame, others seem to have waited much longer.
Can't wait to be in class with my fellow November employees!
