Stanford University Program Associate interview questions

Interview process was engaging and went well, until I was ghosted... I believe there were three or four rounds total, I made it to the one before the last one, which involved some research on their program, creating a slide deck, and giving a presentation. I was told I would be contacted and informed of whether I was selected for the final round or not. I sent an immediate follow up and a one-week follow up - nothing. Never heard back, even several months later. Given that I spent a few hours prepping and conducting the interviews during an extremely busy week at my current job, I felt like my time was disrespected. Seemed great - the people/team, the content, the organization. Unfortunately, the ghosting makes them come off as disorganized, self-important, or both.
