Recruiters for Qualcomm are extremely nice and sociable. They try to help you out as much as they can, and they have a surprisingly depth of knowledge about Qualcomm's technologies even though they aren't engineers.
The 45 min interview was primarily technical, and was administered by a senior engineer. The questions were okay, but the engineer answered his phone ten minutes into the interview and was on it for a good 20 minutes. I thought it was very rude and unprofessional.
