I applied through a staffing agency. The process took 2 weeks. I interviewed at Qualcomm in Dec 2011
Interview
Applied through the company's website, and received the email about the phone interview after about 1 months. The first run consisted of a phone 1:1 interview. You should have a strong math and programming skills. They first went through your resume and asked a lot of questions about your resume, then they asked some questions about elementary math and programming.
Interview questions [1]

I applied online. The process took 1 day. I interviewed at Qualcomm (San Diego, CA) in Dec 2011
Interview
From the phone interview through onsite interview, I interviewed with about 8 different engineers. Questions covered fundamental topics in DSP, wireless communications, linear algebra, and even algorithms. Spent 80% of the time on the whiteboard and was also asked technical questions during lunch.
I'm not going to disclose the specific questions asked, but if you know are well-grounded in the fundamentals and have good communication skills, you will be fine.
