I applied online to Qualcomm some time in February 2014, and heard back a month later. I hate two interviews that were a mix of technical and behavioral questions. The technical questions were centered around C++ or Java. The interviewer was flexible and let me answer based on the language that I preferred. There were some general questions about data structure, heap and stack, and other algorithm based questions. I found the behavioural questions to be fairly detailed. It included experience working with teams, experience with existing code bases. and debugging methods.
