3 or 4 round interview (the on site is 6 hours long). Topics are standard for embedded systems: RTOS, ARM processor, C, and/or C++ trivia. Leetcode questions in both C and/or C++ but no STL allowed (makes the questions a bit awkward).

I applied through a recruiter. The process took 2 months. I interviewed at Apple (Cupertino, CA) in Mar 2026
Interview
The first phone screen was about questions regarding applicant's resume and experience.
The Interview was intense with each interviewer asking a behavioural questions with follow ups and then a technical question with C coding.
I was eliminated after the first round. The process included a recruiter screen followed by a 45-minute call with the hiring manager. We covered role scope, prior projects, and technical depth, but I did not advance to the next stage.
