good, but the HR was nice but the hiring manager was not very welcoming and didn't seem to be listening at all. They did not reach out to give me an update which is not very professional.

The interview process has 5 rounds R1) HR screening R2) Technical discussion with the team leader R3) Live coding #1 R4) Live coding #2 R5) On Site in California with upper management The whole cycle was very fast, it took only 2 weeks for the first 4 rounds. Got stopped after R4. In the meantime another position as Applied research scientist got open, where my profile was a better fit. I asked HR if I could apply for it but didn't get an answer. I then asked the hiring manager, who said that my profile was indeed a good fit and he asked HR to reach out, but at the end they ghosted me. I think I was not such a bad candidate as I reach R4 so I would have expected a more professional communication.
