The process was going fine until the third round. I have been interviewed at Milpitas, CA for the third round. There was no proper communication from HR about flight tickets and accommodation. (The night before I have to start to CA, they have sent me the itinerary and hotel booking information. I was totally clueless till then and not sure about the interview.) I was interviewed by five people. Four rounds went fine. A senior technologist started asking me about Facebook API and was rude and very sarcastic while asking questions. I had great expectations on the Western Digital interview but they didn't ask a thing about Algorithms and Data structures. All my algorithms practice was vain. The interview is only on your resume and not at all about how knowledgeable you are in Computer Sciences basics and concepts.
