First, there was a phone screening interview, which included questions based on resume, computer architecture and memories. The second and third telephonic interview were on computer architecture, mainly focusing on through put , pipe lining , pipe lining hazards, branch prediction ,cache L1,L2 verilog implementation of state machines etc The interviewer gave ample time for answering and even had numerical solved

Phone call with hiring manager, followed by full day of onsite technical interviews with senior engineers. Onsite interviews were easy and fun, office was pretty depressing. Regret going through the process.
