Observe.AI Software Development Engineer III interview questions

Total 5 rounds of interview was completed after which I haven't receive any call backs from the HRs. I tried to reach out to them multiple times and they replied "We are still process of collecting your feedback". It's been 1 month now and they are still assessing my feedback. They don't have the guts to tell us that we are put on hold or rejected. Totally unprofessional company.
