ArcelorMittal Associate Engineer- Intern interview questions

It was a pretty straight forward process. I worked on a project for Am through my university. So when i wanted an internship, I asked them and luckily they had an opening. I was contacted by the HR, I did well in that interview. I was given an offer, because I was recommended by the group I would be working for. So I really do not have too many inputs about the interview process. However, i must mention here that, their full time hiring process is really challenging. I witnessed three interviews and I can tell that you will be tested on all possible fronts if you want a full time job at AM.
