Challenge Manufacturing Engineer interview questions

Their Visitor's waiting area where I was told to report to consists of a kind of a hallway with two plastic chairs, with no lighting except some filtering in from the opaque windows between it and the production area. The chairs were way too dirty to sit in when nicely dressed for a professional interview. The area is completely unattended, without any way of checking in (or checking if you're even still on the schedule when your interviewer does not come to fetch you on time). It had a number of HR fliers with condescending to passive-aggressive verbiage which had me feeling quite apprehensive about wanting to work there by the time my interviewer fetched me. I imagine that the signs are intended more for Production personnel, but still if that's how they treat their labor force for first impressions, I have a lot of apprehensions about the resentments I'd be having to work through when collaborating in cross-functional teams to actually work toward the coorporation's best interests. However, once my interviewer did come for me, I was ushered into a nicer conference room, and both the HR and the engineering representative struck me as friendly, competent, and excited to adapt ideas for improvement from employees, so maybe first impressions aren't everything, or maybe there's a "them and us" atmosphere that I don't want to work in anyway. They never got back to me to let me know their decision, and I didn't ask.
