I applied through an employee referral. The process took 2 months. I interviewed at Qualcomm (San Diego, CA) in Sep 2014
Interview
phone interview: interviewed with a few people from the team that were hiring;
onsite interview: talked to 7 people in total, including the analyst, manger, director and VP.
I had the phone interview in the morning, and then confirmed for the onsite the afternoon. The onsite took about 5 hours, including lunch.
