Qualcomm Senior Engineer interview questions

I applied through internal referral. First phone screen with the manager, which was very general, such as how do you debug an infinite loop in your testbench. In total 4 technical rounds, lunch with manager. 3 technical rounds included basic RTL design questions, and 1 round was about back end. I was able to get an offer around 3 weeks after the interview.

1 Telephonic round 1 Face to face interview ( 3 people interviewed) There was no white boarding but there was code snippets that I had to write in a paper. The hiring manager asked puzzles where they felt the answer was not that convincing.
