AMD interview questions

After a phone screen and initial screening from the hiring manager, invited for a couple of interviews (around 3-4 ) Process was relatively smooth, intervievers were very knowledgable and kind.

At first, was the same with everyone, intro yourself, asking about your final year project and so on but after that there was a technical test for one hour which is so sudden and I didn't prepare for anything...because I was not informed for that. Maybe they wanted a talented trainee.
