Georgia-Pacific Engineer interview questions

Interviewed with recruiter with 2 weeks after online submit. Went very well and was pushed to do a video call with the hiring manager but took a couple of weeks with horrible communication on their part. Interview also went well, and was asked to do an in person interview and tour. Once again to over a month to get ahold of them to reconnect. Went in for tour and interview with 3 sections and I felt it went very well, they were very receptive and provided great feedback. The hiring manager said I would be hearing from them and no communication now for 2 months. I have reached out to the recruiter and to the hiring manager both. Im a professional and of course I moved on, but the demeanor of the higher process managers was horrible.
