Yngen Datacom Corp. interview questions

Good at first however i was kind of confused with the process because the recruiter keeps on contacting me to answer the same assessment all over again then when i ask for a follow up there will no reaponse.

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.
