I applied through the university and had just one interview.

There were two interviews, and both were nice. Both interviewers were Hardware Engineers.

I am mainly focused on software, but this position required both hardware and software skills, so I was interested.

They asked me a mixture of hardware and software questions, mainly hardware. They asked me to write Verilog and C.

Most of the questions were pretty straightforward and basic.

They asked me to write the Verilog code for a D-Flip Flop. I had forgotten Verilog, so I asked them if I could write it in pseudo-code. I derived and wrote the code from first principles. I think this impressed them.
