Qualcomm Machine Learning Engineer interview questions

1 technical round followed by onsite. DS and algo's in first round. Onsite round: all hardware questions. Not sure why they called ML guy for this role. No questions related to my project or machine learning questions. some basic python coding questions.

average interview, ask questions about previous experience, do an online test of coding abilities. And I also ask them some questions. There are two persons are on the phone, One is the team manager and I don't know the other person. They are nice, speak slowly
