Spectro Scientific interview questions

Interview process consisted of 5 rounds of Zoom interviews. After 3 interviews I was invited to a 4th and told this would be the last one. However shortly after, another one was added for later in the day. During this process communication was open and thorough. I was kept informed of the process and where I stood and when a decision was to be made. After the last interview I was told they would be getting together to discuss and make a decision. I had been informed that they wanted to make a decision within the week so as not to keep us waiting and they were down to 3 candidates. After time had passed and I had not heard anything. I felt it was probably not a good sign so I reached out to my recruiter. I never received any further response or communications
