Never felt like an interview and it was a casual informal interaction. It was a very pleasant experience. Nothing to be nervous about! Be prepared to answer lots of questions about yourself.
I applied through an employee referral. The process took 2 weeks. I interviewed at Apple (Sunnyvale, CA) in Apr 2016
Interview
Phone interview followed by 5 hours of in person interviews with various team members. I found that they are proud to work long hours with little balance for a personal life. I didn't end up proceeding since I found the work culture was not a good fit for me.
They also wanted me to come in later to do a presentation on a project I had worked on in the past. Not worth my time.

Question 1
They want to know how you will handle pressure, in an environment that changes quickly. How you lead teams and how you have innovated in your last job.
