CPU performance architect virtual onsite interview @Google

1) can I expect questions related to workload characterization and analysis?

2) any inputs on the level of coding questions to expect? Recruiter broadly said don't expect questions as hard as ones for SWE. Not much specifics

3) I'm preparing fundamentals and advanced concepts in computer architecture and microarchitecture. Should I also cover deeper design related questions as well ?

    Ive done a few cpu engineer interviews before switching to SWE but I'm not a cpu engineer ATM so take this with a grain of salt.

    The things I was asked based off of my memory:
    -> design a n stage pipeline to optimize x operation
    -> implement some basic branch prediction on that pipeline
    -> pros/cons of the design
    -> how would you write code to test instruction space? Test throughput? Energy expenditure?
    -> RISC v CISC pros/cons
    -> domain specific chip vs general purpose pros/cons

    That's all I can remember. Good luck!
