INTELITY Content Writer interview questions

I started interviewing in April of 2022 and had my last in May 2022. I went through four rounds of interviews, meeting assorted members of the marketing team and learning more about what my potential role would be. I was met with positive replies and encouraging words. However, after I sent them a thank you email for the fourth interview, I was completely ghosted. I followed up with different parties I'd spoken with to ask if there was any other questions they had for me. Look, I can understand if you went with a different candidate, but after four interviews and two personal follow up emails on my part, a one sentence 'Unfortunately we will not be proceeding with your application,' reply would constitute the bare minimum. A shame, as I was excited about this position, and would have appreciated any feedback that could have aided in my job search going forward.
