I applied through a recruiter. The process took 1 week. I interviewed at Apple (Austin, TX) in Nov 2019
Interview
Was contacted by a recruiter via LinkedIn who thought my background at my previous employer was a great fit. Had a phone screen and he cut it short stating it went very well and invited me in for a "whiteboard session". The opening was for a hardware engineer position and I was told to "brush up on the fundamentals" which was very broad so I went back and reviewed some material relative to communication protocols like i2c, SPI, PCIe,USB etc and other signal integrity techniques as well as fundamentals like voltage division etc.
The first thing they had me do was derive the gain formula for an inverting op-amp. Which caught me off guard as I would not be working in op-amps nor did I have any familiarity with them for over a year coming from a digital design background. Then we went into some signal integrity questions.
Interview questions [1]
Question 1
Draw an op-amp circuit and derive the gain formula.
Screening, followed by onsite. At least 4-5 hours of interview sessions. Diagramming on white board. Questions on digital design and signal integrity. Tough. Detailed. Also questions on experience and culture fit.

Question 1
Where should you place the capacitor on a power pin?
It was 3 stage process with technical, hr, culture fit round and they asked medium problems with covering basics of the circuits design, digital electronics. And they also gone through cv and asked situation questions
Recruiter reached out and first conversation
Then first and second round of 45 min technical interview. The technical interview need critical thinking and have a fresh mind of all fundamentals of electronics
