Greater Philadelphia YMCA Learning & Development Manager interview questions

Interviewed with the internal recruiter, then the hiring manager, then the team, then the Chief Human Resource Officer, then the VP of IT, and lastly a Site Manager. 6 interviews totalling at least 20 hours including prep and applying. After the last interview, I never heard back. I reached out but they completely ghosted me! Very unprofessional even at the highest level of the company. I tell this story to anyone I know who is thinking of working in the corporate office.
