The whole interview process was divided into two parts.

First, the basic questions covered projects and a brief project explanation.

After that, it moved on to basic questions on pipelining, caches, forwarding, hazard detection, and examples of hazards.

The second interview was much more detailed, covering out-of-order processing, scheduling, and some coding skills.

He asked me, "How to test a 32-bit adder?"

Well, I said, "Under the circumstances that we have the netlist, we can use ATPG to get it done or match it with another perfect adder netlist."

He didn't seem to be satisfied.
