Qualcomm interview questions

I was contacted by a staffing specialist for a telephonic interview at first.I cleared the telephonic round and consequently I was called for an onsite interview.I found the employees,office setup and the interview process to be thoroughly professional.the interview lasted for close to 6 hours in which they focused on the basics of RF design and IC design.

Got a phone call after submitting the resume. 1st round IV with the recruiter. 2nd round IV with the Staffing manager.
