Heaven Please interview questions

I had to wait outside the lift as I was 15 minutes earlier. The interview was held in the entry. Only a small table and 3 seats instead of a room. There were 2 interviewers. One of them is the designer. Another one didn’t even introduce her identity. I did the Self introduction first. Then they asked me some in depth questions about my last job. But they didn’t really know the operation of e-commerce/online selling as they kept asking you the stupid questions and skills of it. They didn’t even introduce their company background. I asked them and their attitudes were rude and not willing to reply my question. They were not willing to reveal their team size and the career path. For this scale of company they have second interview….
