Qualcomm Software Engineer interview questions

Had 3 interviews. They basically asked everything on my resume. First one was from Manager and we had a chat about my projects Second one was a testing engineer and it was like a rapid-fire round where he kept throwing keywords at me like Java, Perl, Module Testing, Application Testing, Stress Testing and I had to tel him if I was familiar with them (Yes/No) Third one was bit technical. They asked some Java concepts I couldn't answer. Coding questions were simple.

I was asked a lot of low level questions in C on memory allocation concepts, Scheduling, etc. Some of the questions were pretty low level. I wasn't prepared for such low level questions ( compilers, memory segments, blah blah).
