Holcim Environmental Engineer interview questions

I first met with my now boss, he asked the basic interview questions. My second interview was with two members of the environmental team whom I would be working with everyday. They mostly told me about what the job consists of and asked me a few questions about myself and my experience. My third interview was with a VP who asked me about my experience, why I want the job, and my college education. He ended the interview by telling me to expect an offer in the next few days.
