Red Points interview questions

I sent a online application and was called for an interview a week later. My first interview was a 30 min with HR. Even though the interview was online, the recruiter was late and did not apologize or even introduced themselves before jumping into asking what I knew about the company. When asked about the WFH policy, they went on a tirade against current employees, criticizing that there were most likely working from the beach, instead of staying in the office' city. In addition to that, during the interview they explicitly told me there was no room for salary negotiation. HR emphasized how very fast-paced and demanding the work environment could be depending on the clients needs, which implied working long hours when needed. That in addition to the criticism of work colleagues gave me the impression that there was a lack of trust towards employees and a high-stress environment. After that interview, I went on to have other two interviews with people from the team. Their questions were very general and mostly based on my experience, background and aspirations. When asked about how the organization within the team & workloads were managed, they mentioned that there was none in place and that the workflow was basically a buffet system, first come, first serve. I understand that a growing company goes through these sort of disorganized times, but the combination of lack of organization, lack of trust and demanding long hours really standed out to me. I was informed that I was among the final candidates for the role and was asked to wait for a week for the final decision. After three weeks and unanswered emails on their part, I believe they must have selected someone at this point. It is only a matter of basic decency and respect for others actually taking the time to write a rejection & feedback email informing of the selection process, especially to candidates that were in the final rounds. I was initially very interested in the company's product and its potential for growth. My experiences with the team members were also particularly pleasant. However, the same cannot be said about the way HR portrays themselves & handles their candidates. I tried to dismiss the red flags thinking that it must have been related to the company's growth but it is evidently clear that it's inherent to the organization.
