I have applied through an employee referral. After one phone screening interview with the hiring manager I was invited to full day onsite interview. I've received a one-time code to Apple Travel system and ordered flight tickets, hotel room and rented a car. All the process was very smooth and fast. The interviewers were smart and pleasant. However, I didn't do well. There were many Machine Learning questions, which I had no experience with, and I've tried to answer them without mentioning the lack of experience (not a good strategy). After the interview they didn't bother to tell me that I failed until I explicitly asked them two weeks later.

I was contacted by a recruiter via LinkedIn. The recruiter asked to have a phone conversation to generally find out whether the position would be a good fit. Very broad and high level discussion. After speaking with the recruiter I was told that arrangements would be made to speak with the hiring manager on the phone for a more technical interview. The phone interview with the hiring manager consisted of coding and technical question Q&A. The coding part was first. The manager also wanted to ask questions about data structures. The technical question part consisted of theoretical questions regarding machine learning and approaches towards solving computer vision problems. No questions were asked regarding specifics on my resume. The expectation was to write code in C++.
