Xantura interview questions

The first round was with the TA team, which was quite straightforward, and I was moved to the Hiring Manager round afterward. I had a very positive discussion with the Hiring Manager. We discussed the role and my experience in detail, and the Hiring Manager mentioned that I was a perfect fit for the position since my experience aligned well with their requirements. I was told to expect a response within 2–3 days; however, I never received any update from them. I followed up four times, but unfortunately, I did not receive any response. They responded to my emails promptly before the Hiring Manager round, but completely disappeared afterward. At the very least, it would have been courteous to provide an update, even if I was unsuccessful, or at least send an automated rejection email.
