Anonymous Employee in New York, NY
I applied through an employee referral. The process took 4 weeks. I interviewed at Qualcomm (New York, NY) in Feb 2022
It consists of 6 interviews, 45 mins each, on the same day. And interviewers were really kind and guided me through questions patiently. Overall the interview was tiring but fun at the same time.
- 1. Write a Verilog code to generate a clock signal at a certain frequency. (a lot of Verilog basic problems) 2. draw a CMOS logic gate 3. Why do you want to be a DV person? 4. What is the most interesting class you took? 5. Other real-life related engineering problems (related to SNR)
