No context was given before the 1st round which was supposed to be a VC but apparently it was a VC only for the candidate and not for the interviewer.

HR contacted through mail and process took 2 weeks to conclude 4 rounds. all rounds were technical, although last round was Hiring Manager who was the director, unfortunately that round didnt go well. What bothered me most, HR just disappeared after last round, I had to reach out to her twice, and then she mentioned that not all rounds were positive, I am still waiting for detailed feedback, lets see if I get response.
