GAF Process Engineer interview questions

I applied on the company website and was contacted for a phone screening. After the phone screening I was scheduled for a virtual interview with the hiring manager. That interview went well and I was then invited on-site to do a panel interview with the hiring manager, plant manager, and one other guy who was completely disinterested in the meeting. The interview was very awkward as one interviewer couldn't understand why I left my previous job and kept coming back to it time and time again. The other interviewer was having a hard time staying awake and it dawned on me. I wasn't being interviewed because they thought I was a potential candidate. I was being interviewed to meet some quota. After the virtual interview and hours of wasted time interviewing and driving to Gainesville, TX, I received a generic email informing me that I did not get the position. Luckily for me.

Went to one of their facilities and toured the production plant. Interviewed with 6 different people of varying engineering backgrounds for about 15 minutes each. Asked questions about content of resume and why you wanted to apply for a certain position.
