Apple Sr Software Engineer interview questions

Applied online. Got recruiter contact me the next day. Had a little conversation about my current work, and expected salary. Hiring manager called me 2 days later to discuss my background and the position he is trying to fill. Recruiter called back saying manager likes me and would like to give me a little coding challenge to complete at home. The question was easy to do (I do that type of coding every day at my current job). Recruiter phoned back with positive feedback and scheduled onsite on Monday. Met with 9 team members including hiring manager and his boss. Mostly conversation on technical questions and behavioral questions, some reasonable whiteboard coding problem but no BS. Offer came in on Tuesday. Quite a generous offer beats my other offers in hand by A LOT. Tried to negotiate a little more but couldn't.
