I applied online. The process took 3 months. I interviewed at Qualcomm (Dallas, TX) in Oct 2021
Interview
Overall the interview was easy. I only had one round of interviews with two engineers from the team. Mainly they went over my Ph.D. research. At last, they asked fundamental questions on wireless communications, signal processing, probability and statistics.
