Qualcomm Engineer interview questions

Was contacted and asked to meet one person. Subsequently went in spent most of a day meeting 5 people. Their interview process seems to be structured for someone who is not very senior. They ask a lot of very basic questions on digital design, DSP, communications. Found that most of the interviewers had a lot less experience and so their perspective is very limited. Out of the 6 people met, in total three seemed to adapt to the level of the person being interviewed while the others stuck to the type of questioning for a mid to junior level person and not the type of interview someone with more than 2 decades of experience would expect. Some of them did not seem to understand the topics they were asking questions on and failed to understand things when alternate solutions were proposed or it was pointed out what they were saying is incorrect.. Sent one of them excerpts from text books subsequently. For a senior person, I woud have expected them to discuss past work experience, and get into technical discussions of past projects and how it relates to what they do, chip architecture, etc. They stuck to mostly simple questions such as synchronization, FIFOS, state machines, C syntax, PERL syntax, etc. Only two or three of them seemed to a have broader perspective, the rest seemed to be run of the mill with no idea as to how conduct a proper interview.
