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.
