      Average interview

      Application

      I applied online. I interviewed at Qualcomm

      Interview

      It began with an introduction of yourself. Then, they take a small amount of time trying to understand what your research is. After that, comes the technical questions on RF basics, statistics, and telecommunication. When the interviewers were done asking questions, it would be your time to ask questions. After that, the HR will take over and maybe ask some behavior questions.
