They sent me an interview invitation, but then completely ghosted me without any follow-up or notification, leaving me confused, frustrated, and unsure about my application status or next steps further. And then, sent me rejection letter 3 weeks after lol

1. GREAT PEOPLE & PERCEPTION OF POSITIVE INTERACTIONS: I truly enjoyed meeting with everyone I spoke with. I came away from each interview believing I made positive impressions, and I gathered a clear understanding of the role and how I would potentially interact with each person. The people were wonderful and I saw myself fitting in well with the team. 2. LACK OF HR PRESENCE IN SCHEDULING: That said, I struggled with the scheduling process overall. It was clear the recruiting team was not involved or aware of how the hiring manager was coordinating interviews, and I believe this contributed to both an excessive volume of interviews as well as multiple scheduling errors. Additionally, I spoke with a total of nine (9) people over the course of ten (10) separate meetings that equated to over 6 hours of interviews in the span of 4 days. Several of these interviews were scheduled very last minute, and even same-day, for large time commitments. 3. HIRING MANAGER REJECTION NOTE: After undergoing the entire interview process, I felt positive, sent emails thanking my interviewers, and awaited next steps. I received a rejection email directly from the hiring manager (not HR) on a Friday evening that complimented me, acknowledged that I was qualified for the role and would be a good team fit but then stated an assumption that I would not be satisfied in the role, even though I was never asked a question to directly address this potential concern in my interviews.
