I applied through an employee referral. The process took 2 weeks. I interviewed at Qualcomm (San Diego, CA) in Sept 2019
Interview
Got a call back after submitting a referral. Had a phone interview and then directly an on-site. The interview process was fairly quick.
In the on-site, I had 5 interviews including HR. Each lasted 45 minutes.
