Qualcomm interview questions

The hiring manager gone through a 45 minute technical interview. They try to understand your background, work experience, and finally technical question in your area. After a successful phone interview, they flew me for onsite interview, where you meet with different engineer. the schedule was tight, and they only have time to ask 30-45minutes. The interview was very technical, going over aspect of firmware development, debugging, implementing c code, and some problem solving question. The problem solving questions are easy if you are just out of school, but it would be difficult for old-timer because you have to remember geometry/Trigometry.
