Intel Corporation System Validation Engineer interview questions

I was interviewed by 5 different managers/leads for different teams. I got drilled on technical questions from System Engineering architecture domain, Server, and hyperscale storage design/data center networking architecture, server components internals & data flow, systems hardware and software testing and a few test scripts questions. Personally, I had experience in these domains so I could answer most of these questions. Overall, the interview porocess was great. I had a great time, meeting new people. The interview took about 5 hrs with a short lunch break. My advice is that you should be Honest and knowledgeable in everything on your Resume. If you don't know an answer to a question, DO NOT try to answer. Just let the interviewer know that you don't know the answer or you have no idea, but you are willing to dedicate your time to learn.
