I am reaching out to you for help regarding my Final round Interview.

I received my final interview scheduling invite a month back. I successfully gave my availability dates and times on the link provided right away.

As these dates have passed, I am yet to receive the date confirmation for the interview. After contacting them for the first time, I was informed that I would get a confirmation at least 48 hours before the interview. It has nearly been a month now; I am trying to schedule this Final interview. I tried reaching out to a few recruiters, but unfortunately, I could not get through.

Is there anyone here with the same problem?
Any suggestions on how can I move ahead?
