Apply on the website, make sure your plaintext resume is readable. Took them about 4-6 weeks to get back to me with a phone screening. I spoke with one of the directors of engineering. He was very nice/sincere and technically apt. Questions were pretty basic about IP3, smith chart, vswr, and how you would make measurements in a lab. The on-site interview consists of 5 technical interviews about an hour each. Almost every interview asked to draw a RF front end architecture and draw/explain how a phase lock loop works. Expect questions about constellations, eye diagrams, RF design challenges, IP3, p1dB, smith chart, amp class biasing, analog RF filters (be perpared to draw elliptic, cheby, butterworth, etc), noise figure, etc. There are some esoteric terms which I was unfamiliar with such as gamma opt(optimum matching coefficient) and beta for FM (modulation index for FM). You really need to be able to answer questions on ALL of these topics. I'd say I aced 4 of the 5 interviews and did okay on one and wasn't offered a job, so make sure you know everything I just described inside and out. There are no behavioral or situational questions. They seem to only care about what you know and not whether you'll be easy to work with. This is a bit disconcerting for people such as myself who have worked on a design team before and know the challenges of working with stubborn engineers.

I apply for the job and I received an e-mail for a phone interview 1 week after applying. The phone interview was with an engineer. It was about things on my resume, and questions about receiver, transmitter, key parameters of LNA, PA, explain each, why we use LNA, why we should be in IF, mixers, antennas. She also ask me lab test equipment I used. I passed the phone interview and had the on-site interview with 5 managers and my recruiter. The MOST important things you MUST know are Smith chart, IP3 and PLL. They all asked me questions about that, and also on filters, SAW, BAW technology. You should also be able to talk about the projects mentioned on your resume. I didn't get an offer because I wasn't ready for the interview, but I learnt a lot.
