Qualcomm interview questions

I had a phone interview with one software engineer, one week later I received an email to bring me onsite. There were totally 8 people to interview me, each one had 40 minutes or so. The questions ranges from language to algorithms to operating systems. Questions were not difficult, but you need to prepare well to answer them.

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!
