They ask for a brief intro of yourself. Then they ask simple engineering questions such as Ohm law, how to calculate resistance, capacitance. After phone interview, you will take an exam and move to an in person interview. A panel of 5 engineers interviewed me and the director was there which made me nervous for sure. They showed a PCB blueprint and asked how I would find the issue in the circuit. Then they made me solve a simple circuit using KVL.
