Qualcomm Engineer interview questions

Online Test for shortlisting which consisted of MCQs from various topics like Operating Systems, C, C++, Aptitude, etc. It was followed by two Technical Interviews and one HR Interview. Main focus of technical interview was Operating Systems, C-language Fundamentals, Pointers and a little bit coding

I applied through Qualcomm career portal. Got a call from HR in a week or two. First round was telephonic screening round. After that 4 rounds of interviews happened, Which lasted for around 3-4 hrs. Interviewers were very polite and made interview process very friendly.
