I said I would need visa sponsorship when filling out the application online. Then, they sent me an interview invitation. I have prepared for this interview for a long time. But when we made a phone call, they asked me whether I was an international student and would need visa sponsorship. I said Yes. And then, they said they don't sponsor and my interview ended. So as I have said I needed sponsorship when I applied, why did you make an additional interview with me if you don't sponsor? It really wasted my time!
