Apple GPU Physical Design Engineer interview questions

I got an email from the recruiter to schedule a phone interview which lasted for 45 minutes. I received a positive feedback from the Recruiter 2 days later and was scheduled for a virtual onsite round. This round consisted of 6 rounds each of 45 minutes with scheduled breaks. Each round was conducted by a different person on a different topic. The questions asked required in-depth knowledge and understanding.

I applied online. I interviewed at Apple.Received an email from HR and scheduled for the followed week. It's an one hour interview. Mostly follows what's on your resume and trying to cover all keywords you listed there. The hiring manager conducted the interview process.
