Intuitive interview questions

A recruiter reached out to me, followed by a call with the hiring manager, which was followed by a full day on site in Sunnyvale. The on site interview had a presentation component along with several 1:1s with the team. This was almost 3 months ago. In the time since, I have been met with constantly moving deadlines to let me know if the role still exists, if the initiative still exists, promises of news "within a week" that keeps getting pushed. As of today, I still do not know if the role exists or I got the job despite several follow ups on my end and positive feedback on my performance. I am not sure why they would recruit me and bring me on site and sell the role to me when they were not even sure if the role had approval. Overall very disappointing experience for a company that says they are mission driven.
