I was asked some basic out-of-order execution questions during the interview. The interviewer wants me to walk through the ooo execution process. I forgot some details and seems he became upset. I have 6+ years' experience in this field, but seems he doesn't care about it at all. No discussion during the interview. The only thing he wanted is someone who can follow his question and give him the answer he wants to hear. I've heard many bad words that the hardware engineers in Apple are unhappy and usually face great pressure. I can feel that the rumor is true from this interview. I will never consider a company with such a culture.

Hiring manager reaches out to you and schedules a telephonic interview The technical round is about an hour long. The interviewer touches upon all the basic concepts of architecture. Overall experience was okay. Recruiter is pretty fast at responding.
