Qualcomm Developer interview questions

A recruter sent me an email to schedule the phone screen after I applied online. The recruiter was very helpful and replied to my email very quickly. I had two phone interviews back to back. The first one just went through my resume and ask me some simple questions in c. I have a feeling that I did do well on the first one. The second interviewer was much tougher. We go through many technical questions, but I did not do well in this part.

Quick and Painless interview process. Got a phone interview 2 weeks after applying online. Phone interview was purely technical, lasted 45 mins. Got call for onsite interview a week after the phone interview. All expenses paid trip to SD. 5 rounds of on-site interviews and got an offer 10 days after on-site.
