Smooth Media interview questions

Recruiter contacted me, two phone interviews, lots of email back and forth. After some back and forth, a one-one interview on site. The 1:1 interview was more of an aggressive interrogation than an interview. Wow. This was very unpleasant.

Contacted within 2 days by a recruiter after submitting for the role online. Extensive 2 call (~3 hours) process with the recruiter to see if there was a professional and cultural fit. Calls went very well so I expected and got an interview with the CEO. We scheduled the interview for the end of the day expecting that if things go well, we would go beyond a typical 1 hour interview. We met and talked for close to 4 hours. Great rapport and things seemed to go exceptionally well. The fit seemed right on both sides (required strong blend of technical and management skills). I didn't expect to hear from the CEO for approximately a week whereas trade shows are a big part of this company's portfolio and he would be out of town. I never heard from them again. I followed up with the CEO and the recruiter multiple times with absolutely no response. Very unprofessional considering the level of the role. Very disappointing. I also heard from a former colleague a month or so later who had also interviewed for the same role and they had almost exactly the same experience. Big red flag. The job posting as been re-posted on the job boards for the past 6 months along with a lower level version of the same role. I suspect this is a role that is more about personality fit than a specific skill set. Seems like a very interesting company and role, but I would worry about transparency and communications.
