Lutron Electronics Project Mechanical Engineer interview questions

Applied through online career services site. Received a phone interview within 2 weeks. Rejected based on GPA (<3.0). From what I've heard it's a great company to start your career at, can't say much beyond that. I thought my phone interview went really well but the first thing I was asked was why my GPA was so low and I was told that HR puts a pretty hard limit on this number.

Applied online and was contacted a month or two later for a phone interview. The phone interview lasted about an hour with general resume questions and a couple of brain teasers that were designed to understand your thought process better. About a week later I was contacted to set up on on-site interview in Coopersburg. I live about an hour away, but was offered hotel accommodations for the night before. Arrived at the Lutron campus early in the morning and was given the Lutron experience tour with about 5 other interviewees each interviewing for different positions. The rest of the day consisted of about a half dozen rounds of interviews. There was a general HR interview, a couple of technical rounds, and the role play. There was also lunch in between and the whole process lasted almost 9 hours. Everyone was really nice and the interview was ran smoothly. I was made an offer about 2 weeks after the on-site interview. Definitely the most intense interview process I went through, but it shows the importance places on finding the right people.
