Tata Communications Frontend Angular Development interview questions

I had 2 rounds through Microsoft Teams. 1st round was technical interview from javascript and angular. It went around 40min and I got call from HR that I cleared 1st round and they scheduled 2nd round with technical manager. 2nd round was fully about my project related questions. It went well. But after that I didn't get any update from HR whether I cleared or not. I tried to reach out HR through mobile and email. But no response. They can tell at least positive or negative. Advice to HR team: whether the result is positive or negative, please update the status to all candidates. Don't be irresponsible and don't make wait to any candidates.
