Called on time, 30-45 minute interview. The interviewer explained what Lutron does. Asked me to walk them through my resume, they ask you to describe each experience on your resume in detail essentially. He asked several questions about each resume experience. Then asked a brainstorming question. Brainstorming Question: You are driving an SUV, you come to a bridge that says weight limit 3500 lbs what do you do. Essentially they are asking you how you would estimate the vehicle's weight with no tools.
