I applied through a recruiter. I interviewed at Apple (Belgrade, Central Serbia) in Feb 2019
Interview
It was nice and friendly with lots of conversation.
I liked it, and I was about to proceed to the Cupertino flight. I wasn't because of the salary range. If it was 20% higher, I would proceed.
6 rounds of interview including management and technical, plus HR round. Time span was about a week. Decision making time was about 4 weeks. Most interviewers barring 1 asked very intelligent questions and understood the responses. Few did not and begged the question do they even belong to the company.

Question 1
A problem similar to rate/time/distance GMAT problem asked by another software architect. I did not expect this as I mostly prepared brain teasers and Java questions. I did not get this correct, but did provide some good mathematical explanation. I've solved similar problem and as with GMAT problems if you don't organize them, you'll never get it right.
