I prepared myself well for the scheduled client interview. I waited for almost half an hour for the client. After waiting, I contacted the client to confirm if they can attend or not. The client told me that they are no longer connected with each other. Guess what? No one told me about it. Even the client was surprised why I am asking them to attend the interview. I asked the HR about it but I did not receive any response at all. They just let me wait during the scheduled interview for nothing.
