I applied online. I interviewed at Qualcomm (San Diego, CA) in Apr 2016
Interview
First round Phone screen by a senior employee followed by a face to face with Manager. Phone screen is technical and face to face is more about the work. That's all.
The interview process went pretty smooth but they asked a lot of technical question regarding your knowledge on C. And they are some heap and stack questions that might throw you off guard. The questions are general programming questions and not questions you practice from leetcode or hackrank.
