Qualcomm Software Engineer interview questions

There was a phone interview, followed by an onsite. The onsite was challenging but not unreasonable. The staff was mostly friendly an responsive, until after the interview. It has been over 3 weeks since my onsite, and no response has been received from the company. I have sent two follow up emails to different people (one in week 3, one at the beginning of week 4) and no response. Guess I gotta read the leaves. Rude behavior.
