Modernizing Medicine interview questions

First was a phone screen with the recruiter who told me that the next steps would be a 4-hour video interview with the team. It took about 2 weeks to set up the interviews and then a very technical SEO challenge was added to the mix with an additional 1-hour video interview with the CMO. The challenge had to be submitted before the 4-hour interview but was only meant to be used during the 1- hour interview with the CMO. The 4-hour interview with the team which was scheduled on a Thursday went very well and I received great feedback. My final interview with the CMO was scheduled for the following Monday but was canceled an hour before it was meant to take place. The recruiter emailed me, which I thought was unprofessional. If you cancel a meeting last minute that warrants a phone call, not an email. Their reasoning for canceling at last minute was that something came up last minute and the CMO didn't have time to debrief with the team. I was told by the recruiter that we would reschedule the meeting and when I hadn't heard anything on Friday I reached out to her directly. I was told that she would be speaking with the CMO on Monday and would get back to me asap. On Monday I hadn't heard back and it wasn't until Thursday that the recruiter asked me to chat with me via the phone on Friday to discuss the next steps. Well, I guess the next steps mean different things to be different people because what it meant to her was that they wouldn't be moving forward with me because I didn't have enough director level experience. So after preparing a 30 + minute PowerPoint challenge on a very specific technical SEO challenge I was never provided the opportunity to present it. If they are conducting interviews this way they should wait until after the 4-hour interview and make sure the candidate is a good fit to move forward with a PowerPoint presentation challenge for the CMO. It's really unprofessional to ask someone to prepare that much only to not be given the chance to present due to a lack of experience which could have easily been seen in the phone screen process - we actually spoke about that. Don't have someone move forward in the process that doesn't have the foundations of what the CMO is looking for. Not sure if this is a lack of communication between the recruiter and the CMO, but it isn't a professional look for the company. I personally wouldn't want to work for a company that doesn't value the time of others.
