Broadcom Engineer, Staff-I, IC Design interview questions

Applied by internal referral. One phone interview and one on-site interview. The whole process takes two weeks. Phone interview covers basic analog and digital circuit knowledge, lasting for 1 hour. On-site interview was in Broadcom Irvine with 6 managers and 1 hiring coordinator, lasting for 6.5 hours. The interview process with each manager was introducing my past project and solving analog/RF circuits. The interview process with the hiring coordinator was about the employee benefit (promotion opportunity, stock compensation, etc).
