I waited for 20 mins but Interviewer didn't joined the call. Asked HR to re-schedule the interview and it is not rescheduled till now, I am not sure what is the issue here, Why there is no communication from HR even I try to call they don't respond.

The interview process started off smoothly, with quick actions and clear communication up until the technical interview. During the interview, there was an issue with the representative not being able to turn on their camera, even though it was a requirement on my end. The interview itself went fine with the usual questions, although the scheduled 30 minutes felt insufficient for a technical interview. Afterward, I didn't receive any feedback for several weeks. When I reached out to HR, I did not receive a response, which I found unprofessional. Overall, I feel that my time was not respected during this process.
