4 technical interviews.
Device physics, circuit analysis, logic, and micro architecture.
1 hour for each interview, 4 different people.
No phone screening because I was already an intern.
No behavioral questions because I was already an intern.
Very broad scope, interviewers were helpful when struggling with technical problems.
The focus seemed to be whether I could get to the right answer, not necessarily that I could get it right the first try.
Device, circuits, and logic were more problem based questions while micro architecture tended to focus on questions about microarchitecture and the reasonings for choices made.
