Broadcom Senior Staff IC Design Engineer interview questions

In the beginning, I was phone-screened by hiring manager. After one week, I was interviewed with the group of the engineering and asked technical question, and introduction of myself. The third time, I was interviewed by director of the group. All of them were nice and didn't ask trick question, but very detailed in technical questions.

Approached the opening through a friend working at Broadcom. Was called for interview directly i.e. there was no telephonic preliminary round. There were 4 rounds of tech interview each of 1 hour length on the first day. After a few days, was called to meet the director who provided the offer letter.
