Apple Verification Engineer interview questions

First, interviewer asked about project in my resume. When I said I did cache design in project, he asked me how to verify cache. I didn't perform very well at this point, then he asked inputs and outputs of cache, which is a difficult question for me, and I just told him how cache connected with related modules. For C++ part, he wanted me to swap two bits of an integer. Last question is about how to design clock gating in verilog.

Applied through Linkedin recruiter. Process took 1 month. Then got a phone interview. The phone interview lasted 40 minutes asking about your projects and a lot of computer architecture questions. It was a senior engineer who took the phone. All the questions are good and some of them are difficult. I failed some of the questions and got a rejection email after 1 week. Very good experience.
