The process took 1 day. I interviewed at Apple in Aug 2011
Interview
Was contacted by HR to setup the interview. Straightforward process to get in touch with the hiring manager. Interview was a different story... one question about my past experience, an explanation about what the department that was hiring was responsible for, and then two technical questions.
First question was related to the position description. Second question was not. Wasn't really able to answer either question in a straightforward manner. Felt I wasn't really given a fair shake (two questions?) and didn't feel like I was asked many (just one) questions related to the job description (which was OS level driver programming in C/C++, Unix scripting and so on).
Around 2 months after I submitted my resume for Apple software engineer position, I got a call from the hiring manager. He asked me what was the good day for the interview. It took half day for meeting 5 people. It was long hour interview for me. Each interviewer spent ~ 30 minutes and asked ~ 4 questions. Each interviewer asked questions in the different areas.
The interview was easy, we talked about technical stuff in-depth: os, drivers. If they think you know something, they would ask you till they find where your knowledge ends. So be ready
