I applied online. The process took 2 weeks. I interviewed at Qualcomm in Mar 2014
Interview
Notified by email, took several days to schedule phone interview.
The interviewer seems make no preparation at all and ask random questions:
1, Describe how the signal spectrum changes through receiver chain of Direct-Conversion Receiver and Heterodyne Receiver, and compare their advantages and disadvantages
2, Give the expression of wt of a MOSFET and derive its relationship with dimensions
3, Name the specs of receiver blocks: LNA, Mixer, VCO, etc
Technical interview is smooth and professional. A hour presentation need to be prepared for phd research. 5 technical interview sessions (4 technical and 1 HR). Questions are basic and interviewer will always give the hint when you are struggling.
