AMD interview questions

Referred by my friend through his manager to manager of that group. Got a call for intial telephonic screening then I got a call for fac-face interview. I was interviwed by 3 persons in 1:1 fasion for around 31/2 hrs. They completely concentrated on Memory related stuff and ofcourse some questions repeated. The best part of interview is thier way of approach, and the technical stuff in their questions. There was no HR round which benifited for say.
