I got phone call from senior engineer to schedule the telephonic interview on next day. Instead of question and answer type interview, it was discussion on what I knows and on my thesis topic. After 3-4 days they said I am selected for on-site interview. There were 6 1:1 rounds, all were technical. All interviewers were good and understanding. Hiring manager seemed bit busy. They covered all the courses and fundamental questions on them. They covered most of the scripting and other skills that is required for this position. On average it was straight forward interview and was not too tough. Questions included VLSI, ASIC, DSP, Microarchitecture and some algorithmic questions.
