Qualcomm Test Engineer Multimedia interview questions

I was contacted by the recruiting manager to schedule my interview. After I gave my availability my interview was scheduled and i was informed as to who will be interviewing me i.e. the interviewer's name designation etc.. The interview process was pretty straight fwd. The interviewer sounded serious and gave no reaction at all.

The interviewer was quite rude. He first asked me how I would fit in for this position. Then he asked me if I knew C/C++, asked a few questions too on pointers and references. He then asked me to write a code (using pointers) to reverse a string using a single array and ping him once done. I used swapping logic with a for() loop. He was happy for the first time! He then threw some testing questions, how would you test a CD rom etc....He did not encourage me while I was trying to answer...Then all of a sudden he said thank you, any questions. He seemed as if he was forced at it and completely disinterested in hiring anybody. Overall the interview was very demoralizing and I took 2 days to get out of it. Phew!
