I applied through a recruiter. I interviewed at Qualcomm in Mar 2020
Interview
Overall, it was a great experience. First round was a phone screen. After clearing that, you are required to provide a 1-hour presentation on your PhD work. This is followed by back-to-back interviews.
Interview questions [1]
Question 1
The questions were primarily related to probability and statistics, queuing theory, optimization, and wireless communications and networking. A strong foundation in mathematics is needed.
