Humint Global Technologies .NET Developer interview questions

I got the interview from this company for .net developer. It took around 2-3 days. They send me twice the interview link and said that to attend it. Both the time I've attended the meetings and both the time I didn't feel they seriously want to conduct the interview. Both the time she said, my interview will conduct with different person but it happened with the same guy only. while interviewing with him, I didn't feel he is much interested in this process and every time he was confused with questions. Sometimes even he was not clear what to ask with me. Totally waste of time twice.
