I applied in-person. The process took 2 weeks. I interviewed at Apple (New York, NY)
Interview
You will usually go through two - three interviews. Each with managers that contribute differently to the business.
All Apple interviews are more so conversations then interviews. As long as your relaxed and know past customer situations that you were involved in, you'll be okay.
I applied online. The process took 2 days. I interviewed at Apple (Santa Clara, CA) in Jan 2016
Interview
The first part of of the process is to be selected for a hiring event, where they bring in about 30-ish people. Current employees sit with a group of applicants, and you just converse with them. If you move on the the second round, they do a group interview. It's very laid-back, and it relieves the pressure off of you individually. If you don't know what to answer, you have time to come up with an answer.
Interview questions [1]

Describe some way you use technology in your personal hobbies or passions.
I applied online. The process took 1 day. I interviewed at Apple (Londres, Inglaterra) in Nov 2015
Interview
Group Interview - Introductions some role play, some team problem solving. The focus was not technical at all. It was basically concerned with what sort of personality you were. As I had never done a group interview, I was very nervous and found it very difficult to be myself as I am a bit introverted. I suspect actors and extroverts will do very well. All other info re: the interview process on this site is more or less correct for the Genius role. There was a lot of marketing of Apple's corporate culture and we had to clap. I found it very hard to clap enthusiastically on command and felt fake. Alas.
