Phone interview with HR, then phone interview with manager who has open rec. Next you get invited to meet with the manager in person, but first you talk to HR. Usual questions, no trick questions. You next get to talk with the department manager, potential co-workers, engineers from the department. I was asked reasonable RF questions, a few questions about Analog and Digital circuits, software, a little RF theory. How parts work, how things work in general. It’s easy and fun stuff to talk about if you know RF, but if you don’t, well you can’t possibly answer the questions.
