AkzoNobel Continuous Improvement Expert - Project Manager interview questions

I had a phone interview with HR. Then a phone interview with the hiring manager. Interview with the manager was very technical. He asked about my experience with Six Sigma and project management. I was then called onsite to Chicago, IL. I was really impressed with their open office concept. I had an interview with the hiring manager, other project managers and the Director of Operations. I was also asked to give a Black Belt Test for almost 1.5 hrs. Overall the experience was good and the team was really nice.
