Corning interview questions

I applied through their website, interviewed by a recruiter first followed by the interview with the hiring manager. The hiring manager showed eagerness in my candidacy and asked a lot of logistic questions too. I was invited onsite for a talk followed by an interview. It all went well, I was further interviewed by another panel and finally by the director of technology from Germany. All of them said that they wanna make a decision by tne end of next week! It's been 2 months and I am ghosted, complete radio silence and once in a while the recruiter keeps telling me that they will make a decision next week, this has been going on for weeks and weeks. I lost trust in the process because of the conflicting information. I am in fact surprised because Corning is such a great and reputed company but the process doesn't represent that.
