Kira Systems interview questions

Applied online. Received email with invitation for a phone interview. Spoke with someone from HR. Given great overview of company, current growth strategy and detailed role overview. Went over the questions I had - which were quite a few and was told to wait for feedback, as my profile would be presented to the panel and assessed. The only thing I would say that would have improved my interview experience would be to provide detailed feedback on why they had decided not to progress. CONTEXT: Kira (through HR) had confirmed I had all the skills and experience required in similar companies, through a similar company growth phase (which is what made me an appealing candidate). I was left to deduce I was either overqualified (years of experience required were lower than what I had) or my salary expectations were not inline with what they had budgeted for, or they had found better candidates. Either way - detailed feedback would have been appreciated.

No respect for anyone's time. I did 4 rounds of interviews. The third round itself was 3 interviews that lasted 3 hours with 5 people. After the 4th round which was a mock test that was outdated they said they were going with another candidate because of my skillset... which was known from the beginning? I wish they didn't string me along, what made it worse is that the entire time they were giving positive and encouraging signs that it was a good fit. One of the interviewers also blatantly went on his phone during the interview.
