I applied online. The typical interview process. I was emailed for a video interview. The interview went great and I was told I would hear back in a few days about the next steps. I tried emailing the hiring manager. However, it's been about three weeks and still no response. This has been a total waste of my time. I would appreciate the courtesy of a reply.

I was contacted by a recruiter on LinkedIn, we had a brief screening call, then I had a call with a hiring manager. I was then asked to complete a "homework" assignment. Next, I had a call with two Partner Success Managers on the team, where I was asked to go through a presentation roughly based on the "homework" assignment. Then I was ghosted without any feedback. In my view, if you have met with a candidate, ghosting him or her is not acceptable. An automatically generated email is a bare minimum, particularly after a candidate spends significant time preparing homework and a presentation.
