Qualcomm Software Engineer 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.

I was contacted for a phone interview and after almost a month was contacted for an on-site interview which comprised of 7 interviews - one with HR and 6 others with technical team members. The scheduling was pretty easy. Most questions were based on basics of programming and resume. Asked about previous work experience. Very software and RTOS oriented interviews. Asked to write C programs and solve some questions for optimizing code.
