I applied online. The process took 1 day. I interviewed at Qualcomm (San Diego, CA) in May 2012
Interview
Several basic questions in wireless communication systems such as difference between wired and wireless networks, advantage of multicast. The interviewer is Indian. He was very nice and patient.

What is the difference between wired networks and wireless networks?
I applied through an employee referral. The process took 5 weeks. I interviewed at Qualcomm (San Diego, CA) in Apr 2021
Interview
I got an email about a phone (screening) interview about two weeks after application. Then, one week later, I was invited for an on-site interview along with 1-hour presentation about my recent research. After one week, I had a virtual (on-site) interview consisting of five individual one-on-one interviews (four technical + 1 HR) right after my research presentation.

Question 1
- First-round question: I was asked about what I have done in detail from my resume.
- Second-round question: 1-hour research presentation and several technical questions on LTE RAN protocols and some basic questions on OFDM and difference between EPC and 5GC, and a few behavioral questions (only during the interview with one HR interviewer)
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.

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.
It was a one hour phone interview that included first introducing yourself, then your previous work experience and for the last 20 minutes included few questions on basic signal processing and wireless communications.
