Alcon Quality Engineer interview questions

They asked about my educational experience and my work experience. A lot of behavioral questions and some about quality regulations. Interviewed with a total of 4 people and had a tour of the plant

I first had a phone interview, which went pretty well. They asked for an in person interview at the Houston campus. I was interviewed by 3 associates, it was very laid back and they were very nice. In the end they closed to job position and reopened it, but didn't alert me or tell me they didn't pick me.
