Cordial Experience interview questions

I had an HR screen, HM interview (30 mins), and then she scheduled an additional 1 hour call the next week. Then peer interview (45 mins), and sales peer interview (30 mins). After that I was ghosted. I asked the recruiter for a follow up and she included the hiring manager in a response to get back to me, but nothing. After investing this much time in the process, not to mention the prep time, it's a bit disrespectful to take someone's time without providing any response.

The recruiter reached out to me and we had a great conversation with everyone on the team. I proceeded 4 rounds in the interview process, but they ghosted me after. After multiple follow ups, I got no response. Maybe the position got filled, but I would have liked a follow up. Poor experience in the later stages.
