Lutron Electronics User Experience Design Co-Op interview questions

It was a phone interview for 30-45 min. I was asked questions firstly around my resume, and by academic background, then asked me to give out more information about the current program I am in. Then they asked me about 1-2 projects, and we started a brainstorm session over the phone. They described a scenario and asked me to envision the user interaction and the interface to solve the problem.
