Robroy Industries .NET Software Engineer interview questions

A person directly called me and asked me to come on site. It was the worst interview experience ever. A day wasted. A person in the interview was sleeping and how can you judge my skills when someone was sleeping. Please let me know. There was an online assessment after that. It was full of bugs and very slow. And when I said I had an issue in the online assessment. no one cared to look into it.
