RFIC engineer interview and how did you become one?

I am preparing for an interview at a company that makes wireless networking chips. It is for the analog portions, not DSP etc. Not sure how I will do given that my background is in power IC chips and my RF knowledge is all from classes and projects.

I would really appreciate hearing anyone's experience in the field and how you started your RFIC career.

Know the RF fundamentals, impedance matching, Smith charts, noise figure, IP3, cascaded stages. Know the basic RFIC building blocks, Gilbert cells, cascodes, current mirrors, active loads. Study some basic RFIC circuits, LNA, Mixers, VCOs, PAs. I ask questions right out of Razavi's Microelectronic book. If you don't understand the concepts, you don't get hired.
