I went through multiple interview rounds, including a final stage with three interviews. Unfortunately, I was rejected at the last step, and as far as I know, the company ultimately did not hire anyone for the position.

First I had an HR interview with general questions about salary my background, expectations, motivation. Then I got a test which supposed to be done in 4 hours. Then I received an email that they will not process with my application further. I kindly ask them for feedback about the test, but unfortunately, I did not receive an email back. It would be professional and helpful if they spend a few minutes on giving reasonable test feedback to the rejected applicants. It was a waste of time.
