Phone interview with HR: Asked about my experience and regarding the position I applied.
Phone interview with the hiring manager: Basic questions about Analog Mixed-Signal Design & Verification, PVT variations, Vth wrt to temperature, my design in my previous company(PLL, LC-VCO design), device physics, etc
Onsite: 5 rounds, 2-3 people took the interview in every round. The team was very cool, the interview went fine and they gave me an offer within a week. They gave me what I asked for so didn't have to negotiate. As it was an experienced engineer position, the questions were more closer to my previous work experience.
