Qualcomm Embedded Software Engineer interview questions

It's an all-coding interview, only few words about the team and the role. Some typical c coding questions, nice interviewer with positive feedback. But before coming to the second round, the opening disappears...

First there was a cellphone conversation with the team leader, He asked me some few question about why do i want to quit my current job and personal details of me, Than he told me that i will be invited to an interview in their offices. There i have asked 4 different questions.
