Had an introductory call which turned into a 1 hour interview. I was curious to hear more about the role and was not given the information to know if this was the role I wanted

I applied for the role in spring 2022 but was rejected. About three months later, the recruiter reached out and scheduled a screening for the same week. The screening went well, and she moved me to the next round - an interview with the hiring manager. The day before the interview, I received an email from the recruiter notifying me that they needed to reschedule the interview because "something came up" for the manager (sure, sure). I asked the recruiter the steps for rescheduling - no response. The day following the canceled interview, the recruiter called to let me know they were no longer moving my application forward. I was annoyed but not disappointed because it would have been eight rounds or something (+ I was iffy about them rejecting my application, to begin with). That in itself tells me that it's not the right workplace for me - if it's going to take you eight rounds to confirm someone is the right fit, then you're the problem, not the candidate. Additionally, I am embarrassed for the hiring manager because we have mutual connections. The recruiter was great. But it may be time for them to take down the job posting since they've been recruiting for this role for months - clearly, the hiring manager doesn't know what she wants and is just wasting everyone's time.
