Qualcomm interview questions

I had 1 telephone interview which went well. I was asked a few questions based off of my resume and the projects I have worked on. Then there were a few questions on C++ OO concepts and a programming question to find if a given number is a perfect square or not and return the square root in case it is. I was called for an onsite interview in a week's time after that. The interview process was pleasant. All the interviewers were professional. I had interviews with 6 people and 2 of them went great, 3 of them were okay and 1 was atrocious.

A notice was displayed regarding internships offered at Qualcomm. Application criteria was 1. Minimum 8/10 CGPA 2. No backlogs 3. Only CS, Electronics, or Electrical students may apply They started with a presentation for the eligible candidates, followed by an aptitude test, results of which were declared about 2-3 hours later. Shortlisted candidates were subjected to 1 technical interview and 1 HR interview after which selected candidates were announced. Both interviews lasted for about 30 minutes each.
