Own Company interview questions

I had several rounds of interviews (at least 5) with different people across the organization, ending with an one-hour presentation that I had to prepare and give to a group via Zoom. Despite hearing only positive feedback and having multiple phone and email conversations with HR afterwards saying they would get back to me very soon with next steps, I was eventually ghosted by this company with no explanation. About two months after the presentation, I received an automated rejection email - like the kind you receive from companies who don't even open your resume or give you a first-round phone screen. It was pretty insulting to say the least that they had taken so much of my time but couldn't take any of their own to at least give me a personalized "we're going in a different direction" rejection.

Hiring manager was not prepared for the interview. Very unprofessional and vague details were provided in describing the culture. Do not recommend if you are a customer success professional. Did not get the impression this was a career organization. Experience level of management and staff is not what I expected.
