Several rounds of interviews, starting with the recruiter, and then the manager. The next round was expanding to the broader team and during the final round it was all day of back to back interviews.
I applied through a recruiter. The process took 4 weeks. I interviewed at Apple (Cupertino, CA) in Oct 2015
Interview
1) An email from a recruiter informing me about the position
2) A scheduled call a week later
3) An onsite interview the following week
4) An offer the following week
It was a speedy process and I am glad that I had the opportunity to come in to interview with a talented team!
