Saint-Gobain Research Engineer interview questions

Speed interview. Half day with 2 other candidates. Started at 7:30am, required to give a 20-30 min presentation 4 times back to back to various groups. Next was a tour of the campus and then lunch. All went very fast. Barely had time to ask questions as I was presenting or answered them most of the time. There was a host who followed me all day which helped a lot. Generally people were exceptionally nice. No curveball questions. Had an answer back in 3 business days.

Received a phone call from HR and noticed me a face-to-face interview with line manager. It was a 1:1 interview and later a presentation to a group. The 2nd interview was with production manager. Since I was new to this field, there was not much technical questions. And the last round was with HR manager and General manager.
