Apple Hardware Engineer interview questions

First phone screening with HR, and then on-site 1:1 meeting with hiring manager was set up. It took about an hour, asking about the technical background regarding the resume. Then, the hiring manager gave a technical question. be prepared to write and explain stuffs on the whiteboard.

The entire process took very very long. Other than a short phone call with the recruiter, I was on site for 4 times -- 1 45 min session with the hiring manager, another 45 min technical session, and then a 1 day long interview. I was called on site again later for one 45 min session for someone who cannot make it for the 1 day long interview. Overall the experience was good. People are friendly and willing to share about their experience and the role I am applying to (despite the fact that they have to keep lots of things secrecy...)
