Qualcomm 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.

1 phone interview followed by 3 1:1 onsite interviews. 2 design groups and 1 verification groups.Questions about FIFO, STA, projects, architecture, cache, perl, C, C++, analog circuit and IQ questions. Mainly basic digital design questions and project on resume. Two of the three guys are very nice. They will ask as detail as possible. So, prepare well.
