Qualcomm RF Software Customer Engineer interview questions

First, he asked about projects I did before. Then, he started asking technical problems about 20 minutes. He asked about 5 or 6 question totally. Last part, he introduced their group and company.

After a friend's reference, it took them about 1 week to schedule a phone interview with me. The phone interview is most about OS(process, deadlock, thread), real-time system and some basic C concepts. They also asked about my past project experiences.
