Qualcomm interview questions

First, the bus takes a long time to schedule. Qualcomm is so big and you have to travel from one building to the other. The HR needs to schedule a bus to communicate. The interview was very difficult. I was asked to derive the conclusion of a Ph.D. thesis. And another guy asked me what is wrong for a emitter degenerated bipolar filter if the Gain of the bipolar is much lower than expected. Anyway, questions are kind of hard to prepare. I missed some easy questions too.

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.
