I applied online. I interviewed at Qualcomm (San Jose, CA) in Feb 2013
Interview
The interviewer called me and described the nature of job at the beginning. Then he started asking me some questions about OFDM. Benefits of OFDM? How to solve ISI? What is frequency selective fading? What is BER of QPSK and BPSK?
Interview questions [1]
