Lutron Electronics Software Engineer Internship interview questions

First is an open-end IQ question, then two easy and simple coding questions. The first coding question is about pass by value and pass by address in C++, the second is fizzbuzz.

I talked to one of their recruiters at a campus career fair. They called me for an interview later that night and I talked to one of their software engineers on campus the next day. The interview is overall not too stressful. They asked me about my resume and my class experience, then asked me some straightforward technical questions.
