It was a round table of random questions from semaphores/mutexes, recursion, past project work (what was difficult problem and how did you resolve it), social questions like how you'd interact with negative feedback or difficult situations (give an example of one that actually happened). Too many to really document. You either know them or not. They were mainly based around the items on my resume.

Hardest part of the interview was the impromptu technical questions. Not necessarily hard but kinda puts you out of your comfort zone. I haven't done any Firmware development for Hard Drive/ SSD components so everything was *new* to me. Overall, I did "OK".
