Authentic Campaigns interview questions

I interviewed for a position here over the course of about a month, and unfortunately had a very disappointing experience. After my initial interview with the CEO, I was asked to complete an assessment that took almost two days. I later advanced to a final 30-minute interview. Following that final round, communication stopped completely from both the CEO and the director as they had no HR/recruiter involvement. Even after I reached out to request a status update, I never received a response. I looked at their page on LinkedIn, and saw someone who posted about accepting the role one day after my final interview, even though I was told they "had more interviews the following week." I understand that not every candidate will receive an offer. But after asking applicants to invest significant time in interviews and a take-home assessment, the least that a company can do is provide closure. A rejection email or even a brief status update would have been greatly appreciated. It also would have reflected much more positively on an organization that positions itself as supporting progressive values.
