I applied online. The process took 4 weeks. I interviewed at Qualcomm (San Diego, CA) in Aug 2011
Interview
you interview with 5-6 engineers/managers and 1 HR. Interviews are very technical, with lot of C/C++ coding questions. few puzzles/analytical questions as well as behavioral questions. Do not be surprised if interviewer has not looked at your resume before coming to see you. Interviews are normally spread across multiple groups located in multiple buildings, so you have to travel quite a bit between buildings.
