I went through three rounds of the interview, the first two were technical where I was questioned about the basics of Semiconductor(MOSFETs related) and the final round was a Competency Based Interview.

Interview at Qualcomm as fresh graduate 1.5 yrs ago. 3 on-site interviewers in 2hrs. Interviewers are nice and know their stuff pretty well. Main focus seems to be the way you think and say, rather than your knowledge tank. Phone interview scheduled 2 days later with department manager. Seems they have known enough for my technical spec, so just some talk to know each other better. Then offer came with 2 wks.
