Qualcomm Senior Hardware Engineer interview questions

It is 2-3 phone interviews followed by on site interview. Mostly are technical questions. The on site interview was a full day event. The interview questions include: low power IC design, noise analysis, op amp, pll, LNA, PA, impedance matching, etc. The persons there are quite friendly. They sometimes give me some hints during the interview.

Applied online through a web job post. Took several weeks before I received a response from HR. Got a call from hiring manager to setup a phone interview. Interview went well and was asked to come to San Diego for onsite interview. Onsite interview also went well and was given an offer a few days afterwards. I was unable to accpet the job since I had already accepted another offer from a different company.
