A recruiter reached out to me via LinkedIn with an opportunity description. Once I stated my interest, I forwarded a copy of my resume, and was required to sign a NDA for any confidential information learned about Apple's current or future designs etc. A few days later, the recruiter reached out to me to set up a phone interview with the hiring manager. The phone interview went very well, and the discussion focused on projects on my resume that directly related to the position. The interviewer was very knowledgeable on the topic and asked VERY detailed questions. At the end of the interview I DID struggle to ask meaningful questions, as most of the answers to the questions I normally ask are confidential and could not be answered. The next day I received an email from the recruiter that they would be pursuing other candidates.

Very straight forward and technical. Started off with behavioral, but spent of the interview time on the technical side. From basic circuits questions to DC-DC converter questions (Bucks/Boost) and DAC/ADC. I would also like to specify that they asked about the behavior of several components (capacitors, resistors, inductors), and their performance on AC - DC circuits.
