Air Liquide interview questions

Just a few questions about family. Also, they are very interested in the projects listed on my resume. Many questions about that. Moreover, they ask about why I don't apply for jobs in my previous company Bayer.

I went to an Engineering Networking Reception, Engineering Job Fair, and their presentation on 3 separate days, speaking with 3 of the 4 Engineers there; one of which interviewed me. Fantastic group of people. I was instantly hooked on their atmosphere and how down to earth they were. After the Presentation at 7:30PM I got a text to schedule an interview for 10:15AM the next morning. My interview went okay, but could have been much better with 8 hours of sleep. This was my first interview ever so I couldn't sleep the night before. I think I did well but I have no basis for comparison. I studied a few things about the company on their website, noted key points to go over, and came up with a few questions of my own to ask for the end of the interview. I enjoyed speaking to everyone I met and wish the absolute best for them whether I get the job or not. I met about 10 other companies/employers over those few days and I seemed to have a much more interpersonal connection with them as if I were more than just another ChE Major. I've yet to receive a response from them but am hopeful for one.
